Remember Shin Lim’s routine is not the traditional three-cup, multi-ball routine historically known as one of magic’s oldest tricks.
Instead, it is more accurately classified as a Chop Cup trick.
A close-up magic effect traditionally performed with a single cup and ball.
For historical and technical context, see the classic Cups and Balls routine and its related Chop Cup variation.

Unlike the conventional Chop Cup, which uses a cup, Shin Lim performs his routine using a shot glass and a ball.
Shin Lim Cup And Ball Magic Trick Explained
Welcome to another post from the Info Ruckus Magic Trick Secrets Revealed series.
Watch Shin Lim’s performance at the official video segment from NBC’s The Tonight Show Starring Jimmy Fallon YouTube channel:
The Behind-the-Scenes Secrets of TV Magic
From the outset, the setup of this close-up magic performance seems unusual and somewhat suspicious.
The host Jimmy Fallon is seated with his back toward Shin Lim.
As the performance unfolds, a possible explanation becomes apparent.
Stooge, Confederate Or Plant In Magic Trick
Firstly, as is often the case with TV shows featuring magic tricks or grand illusions, the hosts or judges may sometimes be stooges (also known as confederates or plants).
In this particular case, the host, Jimmy Fallon could possibly be acting as a stooge or a plant.
They are essentially secret accomplices who work with the participating magicians, playing along to help create and execute the intended magical illusions.
In addition, it also adding humor and making the performances appear more interactive and engaging for the audience.
Furthermore, some key members of the TV production team may also be in on the secrets behind the tricks.
This is because they may need to help the magician set up props and arrange the stage.
They may also coordinate camera angles and shots to ensure the illusions look convincing to viewers.
After all, it is just entertainment, not some top-secret or clandestine operation.
Servante Behind Jimmy Fallon’s Chair
Next, Shin Lim is probably using the backrest of Fallon’s chair to conceal a servante (a hidden holder used by magicians to secretly store or retrieve props).
Glasses Used By Shin Lim In The Tonight Show
One more thing, the shot glass is probably not the genuine The Tonight Show merchandise, despite Shin Lim’s claim
Notice the differences in their design and appearance:
It is his own customized and gaffed glass prop, as you will find out later in the post.
Shin Lim Chop Cup Trick Revealed
How did Shin Lim do this particular ttick?
Let’s get the ball rolling and examine how Shin Lim achieves the ball’s appearances and disappearances.
Types of Balls Used In Shin Lim’s Cup and Ball Trick
If I’m not mistaken, basically there are four (4) different types of balls:
- An ordinary ball made by rolling up adhesive tape.
Interestingly, we never actually get to see Fallon finish rolling up the orange tape into a ball clearly.
That’s because the ball is secretly switched in Shin Lim’s hands at 1:35, after which the original ball is palmed away.
2. A gimmicked rolled-up tape ball
This is the substitute ball that Shin Lim secretly switches in when he takes Fallon’s rolled-up tape ball at 1:35.
This appears to be a gimmicked tape ball, possibly using a magnet or a small piece of adhesive tape to attach it to the glass.
3. A solid ball possibly made of resin, acrylic or plastic.
It seems to have a small loop or attachment point that allows the Invisible Thread Reel (ITR) thread to hook onto it.
4. Then there is the fourth ball, which is actually a set of nested spherical containers, similar in principle to nested boxes.
It consists of progressively smaller containers that fit inside one another, concealing the initialled coin within shown at the end of the routine.
Shin Lim Cup And Ball Trick Routine
At 1:31, as Jimmy Fallon rolls the orange tape into a ball (1), Lim’s right hand moves toward the servante.
It appears he is retrieving a pre-prepared tape ball (2).
I think this gimmicked ball (2) comes with either a sticky tape or a magnet.
After Lim picks up the rolled-up tape ball (2) with his left hand and palms it.
Under the guise of shaping it with both hands, Shin Lim appears to switch the newly retrieved ball (2) with Fallon’s rolled-up tape ball (1).
At 1:39, Shin Lim hands Ball (2) to Fallon while secretly palming Fallon’s rolled-up tape ball (1) in his left hand.
As Shin Lim turns around to pick up the shot glass at 1:41, he slips his left hand into his pocket, apparently ditching the palmed ball (1), which is no longer used in the act..
After handing the glass to Fallon, Shin Lim once again moves his left hand behind the chair’s backrest at 1:45, possibly retrieving another ball (3) from the servante.
At 1:44, Jimmy Fallon doesn’t simply drop the ball (2) into the glass.
He appears to be very cautious, turning the glass around before dropping the ball inside.
Shin Lim then immediately snatches the glass away from him.
Perhaps this is to prevent the gimmicked ball from accidentally sticking to the glass surface behind the printed label design.
Shin Lim One Glass and Two Ball Trick Explained
Now at 1:48, after taking back the shot glass containing the ball (2) from Fallon, Lim has another ball (3) palmed in his right hand.
As Lim turns toward the table, his hands are out of the camera’s view briefly.
At this point, there are two different balls (2) & (3) in play.
Shin Lim secretly sticks the ball (2) is inside the shot glass, hidden from view by its printed label design.
The other ball (3) is a solid ball, which Shin Lim places on top of the inverted shot glass.
We will get back to the balls later, now let’s look into the signed coin sequence.
Is The Signed Coin An Original Or A Duplicate?
Many YouTube and Reddit commenters pointed out that Shin Lim never actually dropped the initialled coin into Jimmy Fallon’s coat pocket.
If you watch closely at 2:27, you can see Lim’s thumb and index finger moving slowly behind Fallon’s back.
They could be right.
First, the coin is rather small, making it difficult for the live audience to see clearly.
Furthermore, Fallon never showed the coin to the viewers to establish that it was blank or had not yet been initialled.
It is therefore possible that he was merely pretending to write the letter “J” on a coin that was already initialled.
This raises the possibility that Shin Lim used duplicate coins.
One that disappears earlier in the performance and another that is revealed inside the nested containers at the finale.
Why do I think that?
Remember, at the beginning, I suggested that Jimmy Fallon might be a confederate or stooge in this routine.
If that is the case, the signed coin could have been placed inside Fallon’s coat pocket before the show even began.
I also believe at 2:27, Shin Lim deliberately draws attention to his thumb and index finger pinching together, creating the impression that he is still holding the coin.
He performs this movement rather slowly, making it even more convincing and wanting to mislead the audience.
As a master of sleight of hand, Lim could easily have palmed the coin, without drawing much attention to his hands.
So why make such an obvious pinching gesture of the thumb and index finger?
Remember, at the finale, when Lim reveals the initialed coin inside the nested containers, Fallon never shows the audience that the coin has actually vanished from his coat pocket.
At the end of the show around 6:06, Shin Lim playfully drops the coin into Fallon’s pocket.
Is it a sucker callback?
Shin Lim Marker Pen Attached To A Pull
Next, at 2:04, when Shin Lim removes the cap from his marker pen, the way he holds the cap in his left hand suggests the use of a mechanical device known in magic as a Pull.
You can also notice the unusual handling at 2:29, when he brings the cap towards Fallon to put it back on the pen.
This is because he needs to maintain his grip on the pen cap, which is attached to a retractable cord concealed inside his vest.
As he walks towards the table, he briefly transfers the attached pen to his right hand.
This frees up his left hand to retrieve the clear market pen-like device from the back pocket of his pants at 2:34.
I suspect it is an Invisible Thread Reel (ITR), a magic utility device used to secretly retract, maintain tension on, or animate invisible thread.
Invisible Thread Reel Prop Exposed
Interestingly this supposed to be a hidden prop, Invisible Thread Reel is already clearly seen right from the start of the show at 0:14.
It is hanging on the back pocket of his pants.
That is the transparent-loooking device that Shin Lim transforms it from a normal marker pen.
The Marker Pen Transformation Magic Effect
By 2:36, he is actually holding two items in his left hand.
One is attached to the marker pen with the Pull retractable cord.
The other is the Invisible Thread Reel, which remains concealed in his palm, as shown below.
At 2:52, his left thumb keeps the cord in position while his right hand pulls up the attached marker pen.
The cord is difficult to see because its black colour blends into his black shirt and vest.
In magic, this concealment technique is known as Black Art, where a black object is camouflaged against a black background.
For clarity, I use the white dotted line to indicate the black retractable cord in the visual below.
He then releases the marker pen, allowing the Pull to retract it into his vest.
At the same time, he brings out the Invisible Thread Reel concealed in his left hand.
Invisible Thread Reel In Action
After tapping a few times at the ball (3), at 3:00 mark, it appears he is hooking the invisible thread of the device to the tiny loop at the ball.
Note: For a clearer view of the move, slow down the video playback speed to 0.25×.
Then he draws back the reel device, and now the ball (3) is attached to the retractable invisible thread.
The ball (3) is still concealed inside his tightly clenched left fist.
How Shin Lim Transfers Ball Hand To Hand
This is how he transfers the ball from his left hand to his right hand.
As he lowers the reel device in his right hand at 3:06, Shin Lim abruptly brings both clenched fists together.
At that precise moment, his left hand releases the restrained ball (3), allowing the retractable thread to pull it up into his right hand.
Note: To spot this covert move, slow down the video playback speed to 0.25×.
As the result, the ball (3) appears to have mysteriously vanished from his left hand, because now it is in his right hand.
Before revealing the ball in his right palm, he transfers the Invisible Thread Reel to his left hand.
The ball remains attached to the Invisible Thread Reel, which he now holds in his left hand, as shown below:
Next, at 3:16, to make the ball magically return to his left hand, he brings his two closed fists together once again, allowing him to perform the secret move.
He releases the ball, which has been restrained inside his right palm, allowing the Invisible Thread Reel to retract it back towards the device in his left hand.
At 3:20, as he displays his empty right palm, he seems to subtly push the reel device downward into his left palm, disengaging the thread from the ball.
At 3:22, he can now turn the device around, because the ball resting in his left palm is completely free from the invisible thread.
Lapping In Magic Trick
The next move is known as lapping.
At 3:24 he secretly slides the Invisible Thread Reel over the edge of the table and into the servante (a concealed holder behind the table), making the device disappear from view.
From this point onward, I believe Shin Lim relies heavily on the gimmicked table to accomplish most of the effects performed on the tabletop.
Dream Table Pro By Gee Magic
The specially customized table appears to be similar in design to the Dream Table Pro by Gee Magic.
For example, when Shin Lim makes the ball disappear from the tabletop at 3:36, it is most likely accomplished using the table’s hidden gimmick. (watch this).
At 3:49, he gives the shot glass an abrupt, forceful shake to dislodge the ball, which is actually ball (2), concealed behind the glass’s printed label, as mentioned earlier.
At 3:54, he does not actually drop the ball into his left palm.
Instead, the ball remains concealed behind the glass’s printed label.
Similarly, at 4:00, when he produces the ball from the glass, he gives it an abrupt shake to dislodge it.
On both occasions, the ball does not roll freely, but appears to stick momentarily to the tabletop.
This suggests that it may actually be a small ball of rolled-up adhesive tape, rather than the solid ball (3).
When Shin Lim makes the glass disappear from the tabletop, I believe he is using the hidden mechanism of the gimmicked table again.
Then, at 4:19, when the glass reappears, it is once again made possible by the table’s gimmick mechanism.
Shin Lim Uses A Gimmicked Glass
However, this time, he produces a different glass, which appears to be specially gimmicked.
It is probably similar to the transparent cup-and-ball prop known as Over Clear by Jin Hyung.
The internal structure appears remarkably similar to Jin Hyung Han’s Over Clear.
You can even see the edge of the gimmick piece inside the glass.
Looking closely, we can see a curved component and a noticeably blurred section inside the glass.
We will explore how Shin Lim uses this gimmicked glass soon.
Rigged Magician Table
The rigged table also appears to play a role in creating the smoke effect inside the glass and making the ball inside vanish.
So, is the ball he picks up from the tabletop and drops into the gimmicked glass at 4:45.
Note: At 4:48, when he picks up the glass from the table, you can see the ball inside suddenly dart to one side of the glass by itself. This quick, unnatural movement suggests that a magnetic force may be at work, possibly generated by a mechanism concealed within the table.
To see it clearer, slow down the playback speed to 25.0x.
Secret-Compartment Glass
At 4:56, he appears to stick the ball against the outside of the gimmicked glass.
The orange ball that subsequently appears inside the glass may actually be produced by the glass’s internal gimmick.
In fact, the orange object may be a flat, orange-coloured disc rather than a solid ball.
It appears to have little or no depth and remains stationary inside the glass.
Notably, Shin Lim never clearly displays the object to the audience in a way that establishes it as a solid, spherical ball.
He then gives the glass a quick shake (off the camera view), and this may allow the disc to slip back into the glass’s hidden compartment.
Next at 5:06, he holds the glass with his right thumb pressed against the ball that is attached to its outer surface.
He then gives the inverted glass a sudden, forceful shake over Fallon’s outstretched palms, making it appear as though the ball is dropping out from inside.
Interestingly, if the ball were genuinely loose inside the glass, he could simply tilt it and let the ball roll out into Fallon’s palms.
At 5:09, he palms the glass and presumably drops it into the servante hidden behind the backrest of Jimmy Fallon’s chair.
To make the glass reappear at 5:20, he once again relies on the hidden mechanism of the rigged table.
This time, the table may secretly introduce a prepared glass containing a series of nested orange balls,
This time, he uses a prepared glass containing a series of nested orange spherical containers, with the duplicate signed coin already concealed inside the innermost container.
The Psychology Of Shin Lim’s Cup And Ball Magic Trick
What makes Shin Lim’s cup-and-ball routine in The Tonight Show fascinating is not just because of the gimmicked props, and the clever sleight of hand.
A huge part of the deception comes from psychology.
In fact, even when the audience is looking directly at his hands, they may still fail to notice what is happening right in front of them.
This is because our brains do not process everything we see equally. Magicians like Shin Lim take advantage of several psychological principles to control what we notice, what we remember and, ultimately, what we believe we have witnessed.
Let’s look at some of the psychological techniques that make this performance so deceptive.
1. Misdirection: Controlling Where You Look
One of the most important principles in magic is misdirection.
Contrary to popular belief, misdirection does not necessarily mean making the audience look away from the secret move.
Instead, it is about directing their attention towards something else that seems more interesting or important at that particular moment.
For example, when Shin Lim brings his two closed fists together to transfer the ball using the Invisible Thread Reel.
The audience naturally focuses on the apparent magical action of the ball moving from one hand to the other.
Their attention is occupied by the mystery of the effect rather than the subtle mechanical action taking place between his hands.
This is known as attentional misdirection.
The magician exploits the fact that our attention has limited capacity. When we concentrate on one event, we become less likely to notice other movements happening simultaneously.
2. Change Blindness: Missing What Changes Right Before Your Eyes
Another fascinating psychological phenomenon is change blindness.
This occurs when people fail to notice a change in an object or scene, even when that change happens directly in front of them.
Shin Lim uses several apparent object switches throughout the routine.
For instance, the original orange tape ball rolled up by Jimmy Fallon may be secretly exchanged for a prepared gimmicked ball.
The audience sees the ball being handled continuously and naturally assumes it is still the same object.
They have no particular reason to suspect that one ball has been replaced by another.
This is where change blindness becomes particularly effective.
The audience is not necessarily failing to see the switch because it is impossibly fast. Rather, the surrounding actions and continuity of the performance make the substitution difficult to recognise.
3. Misdirection Through Natural Actions
Magicians also rely heavily on naturalness and motivation.
Every movement should appear to have a logical purpose.
For example, when Shin Lim brings his hands together, transfers the Invisible Thread Reel or reaches towards the table, these movements are presented as ordinary parts of handling the props.
The audience sees a performer manipulating a ball and a glass, not someone secretly operating a mechanical device.
This is closely related to the psychological concept of inattentional blindness.
When our attention is occupied by a particular task, we can completely overlook other visible details, even when they are right in front of us.
The secret action does not necessarily need to be invisible. It only needs to remain outside the audience’s attention.
4. Cognitive Bias: We Believe What We Expect to See
Another powerful psychological principle is confirmation bias.
Once the audience accepts that Jimmy Fallon’s rolled-up tape has become a magical ball, they naturally continue to perceive it as the same ball throughout the routine.
They do not automatically question whether Shin Lim has secretly introduced a duplicate or gimmicked ball.
Similarly, when the ball appears to disappear inside the glass and subsequently reappears, the audience tends to interpret these events as one continuous magical transformation.
They are less likely to consider alternative explanations involving hidden compartments, duplicate objects or specially prepared props.
This is also related to top-down processing, whereby our brains use existing expectations and assumptions to interpret what we see.
In other words, the audience does not simply watch the performance. Their expectations help construct the magical experience.
5. The Power of Convincing Gestures and False Assumptions
One particularly interesting aspect of Shin Lim’s performance is how he uses gestures to reinforce an illusion.
Consider the signed coin sequence.
When he slowly brings his thumb and index finger together behind Jimmy Fallon’s back, it creates the impression that he is still holding the coin.
This is an example of how a convincing gesture can reinforce an audience’s assumption about an object, even when that object may no longer be there.
In magic, this is closely related to false transfer and retention of vision techniques.
The magician creates the impression that an object remains in one hand, even though it has secretly been removed or transferred elsewhere.
The audience mentally retains the image of the coin being held between his fingers.
This is particularly effective because people tend to trust what they believe they have just seen, rather than constantly questioning every movement.
6. The Sucker Effect: Making the Audience Feel Clever
Another interesting psychological element is the sucker effect, sometimes called a sucker trick.
This happens when a magician deliberately gives the audience the impression that they have figured out how a trick works, only to surprise them with another unexpected revelation.
In Shin Lim’s routine, the signed coin sequence offers an interesting example to consider.
The audience may suspect that the coin has never actually been placed inside Jimmy Fallon’s pocket, or that a duplicate coin is being used.
But the finale introduces another layer of mystery when the initialled coin is revealed inside the nested spherical containers.
The audience is left wondering whether their earlier assumptions were correct after all.
This creates an additional layer of deception because the magician is not merely hiding the method. He is also playing with the audience’s expectations about the method.
The Final Takeaway: Magic Happens in the Mind
Ultimately, Shin Lim’s cup-and-ball routine demonstrates that successful magic is not simply about hiding objects or performing incredibly fast sleight of hand.
It is about understanding how people perceive the world.
Through misdirection, carefully timed gestures and psychological techniques, magicians can make audiences overlook secret moves happening right before their eyes.
The cleverest part is that spectators may be looking directly at the magician’s hands and props without noticing what is really happening.
In magic, seeing is not always believing. What you see may not be what actually happened.
