This illusionette was manufactured by various people, so it comes with various names, which include: Warlock’s Amazing Frame, P. W. Glass Penetration, Peter Warlock Glass Penetration Mystery,Warlock Glass Penetration,  Davenports English Glass Penetration and English Glass Penetration by Harry Stanley.

There is another version called “Soft Glass by Abbott’s” by Abbott’s Magic Company.

Abbott's Soft Glass Trick Secret

Magic Wagon also came out with its version in 2020, called the Atomic Glass Penetration.

Effect:

A square wooden frame has four quadrants window that sits on a platform holder.

Apparently there is a piece of glass in each four windows.

Two wooden panels with holes are placed over the first two glass panes, one in front and the other behind.

They are held together by a slotted grip on top of them.

The thin metal rod with a length of ribbon attached is then pushed through the holes, apparently penetrating the glass.

Next, the panels are removed and do the same routine over the next two glass panes.

Again the rod manages to go through the solid glass.

Now all the four glass panes are covered with the panels and the metal rod is then continuously pushed through each one.

In other words, now all the four holes are now inserted with the ribbon at the same time.

This is to prove the metal rod could pierce through all four of the glass panes.

After removing the ribbons from the four holes, comes the big surprise.

It is not two or four separate glass panes, but just ONE solid sheet of glass.

I could not find any Peter Warlock Glass Penetration demo video online, so I am using Magic Wagon Atomic Glass Penetration video to explain.

Watch the Atomic Glass Penetration or Peter Warlock Glass Penetration Mystery video:

So how does the Atomic Glass Penetration or Peter Warlock Glass Penetration trick work?

I do not own this glass penetration trick, and neither do I know how the actual trick is done.

It’s my two pennies’ worth; based on my assumption by watching those YouTube video clips.

The secret of this Peter Warlock Glass Penetration or Atomic Glass Penetration is by moving or shifting the glass sheet within the frame.

I do not know how the glass sheet is moved in Peter Warlock Glass Penetration, but Atomic Glass Penetration, it uses a hidden device.

Secret Glass Slider Lever

The main secret of this trick is what I called it a glass slider lever.

It is a built-in device to shift the glass within the wooden frame.

This small contraption is on the performer’s right hand side of the prop facing him.

To be exact, it is located on the frame platform.

In fact I already knew there is this hidden device, before I managed to capture it from the video clip.

See this captured image from the video at 0:31.

NOTE: You can see this hidden glass slider lever clearly when you slow down YouTube playback speed to 0.25.

Here is image captured from the demo video by Brother Bor, where you can see the small device at 3:08.

I think this is where the secret glass slider lever is situated.impossible glass penetration

Now, let’s analyze how the performer handles the prop.

Right from the beginning, at 0:07, as he lifts up the cloth, he rotates the side of the prop with the secret glass slider lever towards him.

After putting up the front panel, he spins the frame around to fix the back panel at 0:26 to 0:30, you can see his left hand holding onto the platform base and the circular board.

Actually his fingers are hiding the secret glass slider lever.

At 0:33-0:34, his right thumb adjusts the glass slider lever, shifting the glass to the right hand side, as his left hand slots in the grip holder on top of the frame.

It is a neat misdirection.

You can see the slight movement of the glass moving toward his right hand side.

From 0:40 when he inserts the white feather through the two holes, he just turns the glass frame slightly, so that the glass slider lever cannot be seen.

Next he performs the penetration illusion on the other two glass windows with a white silk hanky.

First, he adjusts the slider at 1:03-1:04 to move the glass back to the left side, while his left hand removes the grip holder on top of the frame.

Then only he can slide both panels to his right side of the frame, without exposing the left side windows covered with only half glass.

The next move is another flawless misdirection.

As he is putting on the grip holder with his left hand, his right thumb sneakily adjust the glass slider lever at the same time at 1:15.

He pushes in the silk hanky through the bottom hole first, then only he spins the frame around.

The white silk hanky is now safely blocking the secret glass slider lever.

Davenports English glass penetration

To remove the hanky, he must spins the frame back at 1:47, so that the glass slider lever is now facing him, then only he can remove it.

After removing the white hanky, before he slides the two panels to his left, he must bring the glass back to his right side.

Or else you can see the right side windows with half-missing glass.

At 1:56, using his thumb he adjusts the lever again to shift the glass back to his right hand side of the frame.

Then only he slides the two panels to his left side.

While his left hand is still holding the two panels, his right thumb secretly adjust the lever at 1:59.

This is to slide the glass back to his right side of the frame.

Then he covers the right side windows with two more panels.

Now all the four glass windows are hidden.

And remember at 1:59, he has already shifted the glass to the right side of the frame.

In other words, half of the windows on his left is already without glass.

He starts to pierce the thin rods with ribbons through the left windows first.

rod through glass trick

To prepare the right side windows for the penetration trick, again he uses his right thumb to adjust the glass slider lever at 2:39-2:40 toward his left side.

This is an important part of the routine.

When the glass is slid over to the his left side of the frame, it pushes or squeezes the two inserted ribbons.

That will cause the ribbons to be dragged in slightly, which can be seen, just like in this video at exactly: 1:45.

You can see the end of the red ribbon slithering into the hole.

So is this video at 1:14, when he turns the glass slider lever.

You can clearly see the red ribbon being pulled into the top hole!

But for this performer, to distract the moving ribbons from being seen, he turns the prop slightly, while his left hand busy segregating the two streaming ribbons.

This segregating action is actually to pull the two soft ribbons slightly towards the left side, while he pushes the glass toward the left side.

He does this move, so that you would not notice the slight movement of the two ribbons being crushed or pushed out by the edge of the glass.

Now he can insert the two rods through the holes on the right side of the frame.

To show you the four slim rods truly have penetrated through the holes, he spins the prop around slightly.

Again, his right hand covers the glass slider lever.

To finish the trick, he needs to remove the two right ribbons first.

It is because the glass is still over to the left side of the frame, squeezing the two ribbons.

Then again using his right thumb he slides the glass toward his right side, at 3:12-3:13.

To distract you from seeing his secret move, he does it, as his left hand pulling out the two thin rods on the circular wooden board.

Glass Penetration revealed

After removing the ribbons and panels, he still rotates the frame just slightly around 45 degree, so that you cannot see the secret glass slider lever.

Finally he removes and reveals that it is actually one piece of glass with no holes.

Peter Warlock Glass Penetration Exposed

For the Peter Warlock Glass Penetration to work efficiently, the width and thickness of the glass are important.

Look carefully the width and the thickness of the glass when the magician lifts it up from the frame.

glass penetration illusion explanation

It is just slightly wider than the whole window.

To confirm it, here is an image taken from Brother Bor’s video, where you can actually see the width of the slot for the glass sheet.

Magic Wagon Atomic Glass Penetration

From here you know the glass sheet fits comfortably within the four windows.

In other words, this piece of glass has ample space to shift side to side within the wooden frame.

Peter Warlock magic tricks

When the sheet of glass is push to the very end of one side of the frame, you can see the gap is about half of the width of the window.

So there is enough empty space for the thin rods to be to inserted right in the middle of the windows.

When it comes to final part of the trick, one side of the frame already has the ribbons through it.

So to thrust through the other side of the windows, the magician still can slide or push the glass over to the side.

It is because the ribbons are flat and soft, they do not take much space.

The so-called rod is actually more of a knitting needle.

It is rather thin in size.

There is still enough room to accommodate the slim metal rod and the soft flat ribbons against the edge of the frame.

The other items used to show the penetration effect are equally soft and flexible: feather and flimsy handkerchief.

Deceptive Square Attached Pieces

I am talking about the two square shape attached pieces with the black covering on the panel for the holes.

Why do they have such a obvious-looking piece (size and thickness) for such a small opening.

penetrating glass magic effect

It can be more than just as a design feature.

It will mislead your visual perception; you may see it a big hole in the glass.

The truth is it only uses a slim rod, a pliable feather and silky scarf to do the penetration effect.

Soft Glass Abbott’s Magic

There is another version called Soft Glass by Abbott’s Magic Company.

Abbott's Soft Glass Trick Secret

Below is an image captured from the video by Andy Martin demonstrating the Soft Glass by Abbott’s Magic Shop.

You can see the width of the glass sheet is much narrower that the wooden frame.

Hence, the Soft Glass wooden frame has ample room for the glass to slide side to side.

I believe the device to move the glass sheet of the Soft Glass by Abbott’s Magic is also behind the apparatus, as indicated below.

Liquid Glass Stage Illusion Secret

The Liquid Glass Stage Illusion is a bigger version of the Peter Warlock Glass Penetration.
It is created by Jim Steinmeyer, a designer of magical illusions and theatrical special effects.

The secret of “Liquid Glass Stage Illusion” is also by shifting the glass sheet within the frame.

In fact, the glass sheet goes all the way to the uprights (legs or stands) of the prop or apparatus.

There is a similar glass penetration stage illusion idea by Sir Felix Korim, called the “4th Dimensional Glass“.

A sheet of clear glass is pierced with a steel needle threaded with a ribbon.

Again, the secret is by shifting the glass sheet which has a hole hidden behind the metal clip.

It is like the vintage “Glass Penetration” by Floyd Gerald Thayer.

The Flexible Mirror Magic Trick Revealed

This is another trick which the glass or mirror needs to be shifted so that the penetration effect is possible.

Doug Henning Flexible Mirror

The popular Flexible Mirror magic trick (used to be called Bending Glass) created by British Magician Oswald Raetrick also uses the same method.

To achieve both penetration and bending effects, about a third of the mirror has to slide back into the wooden frame.

The bending mirror magic trick apparatus used by the late Doug Henning is by Wellington Enterprises.

The width of the mirror fits right to the edge of the window of the wooden frame, as shown in the picture below.

This is the original position of the mirror within the frame.

Needle Through Flexible Mirror Magic

Just before the trick, the mirror drops down to the side of the wooden frame with the slot.

For his prop, the mirror is still within the wooden frame.

In addition, this Needle Through Mirror trick has a ingenious hinge sign which makes it appears it is folded in half.

Doug Henning Flexible Mirror Secret RevealedCheck out the picture below and see how it creates the illusion of folding or bending the mirror in half.

The frame can be bent right up to almost the middle as indicated.

Look at the edges of the frame and his hands position, you can see it is NOT bend into half.

Furthermore it uses a snug fitting stretchy knitted bag, which makes the magic effect more convincing.

But as for the Flexible Mirror by Ickle Pickle Products, a section of the mirror drops out from the slot to the bottom of the wide cloth.

That’s why it uses a wide and loose cloth bag.

This is the slot at the wooden frame.

Watch closely at the cloth bag in this video, you can see the impression of the mirror dropping out of the frame into the bottom of the bag at 0:40.

Magiro’s Miracle Mirror Penetration Revealed

I think the Miracle Mirror Penetration also uses the same method like Peter Warlock Glass Penetration or the Atomic Glass Penetration.

It is by moving the mirror into the side frames.

As you can see the green wooden frame is rather wide.
