My opinion how it is done is by observing how they handle the U-235 magic trick props.

Definitely this penetration effect uses only one steel ball.

I think there are two secrets in this steel ball through glass trick.

Both the aluminium cylinder tubes are gimmicked.

The plate is not rigged, however it plays a part in the trickery.

Hence, the U235 Thayer CW set comes with the ceramic plate.

It looks like there is an opening at the bottom edge of the top tube.

This cut-out part is facing backward throughout the act.

Hide The Secret Hole

In the Reddit video, the performer does not present the top cylinder tube to the viewers.

He focuses only on the thick glass, the bottom tube, the steel ball and the plate.

However in the China Magic video, the performer shows the top tube.

But he does it deftly, without displaying it openly to the camera.

He holds the cylinder tube up, with his fingers blocking the cut-out at the bottom at 0:29.

Again after the act at 0:45, he holds it the same way.

Then when he places it back on the table, the side with the cut-out facing backwards.

In fact, all the performers also handle the top tube in the same manner, as seen below.

Now we know where and how the steel ball or the stone ball comes out from the top tube.

That’s through the cut-out at the bottom of the tube.

In other words, the steel or stone ball slips out and rolls off the edge of the glass or the cell phone.

How Steel Ball Rolls Out Each Time

But how to ensure the steel ball would definitely roll out through the back bottom hole every time?

The bottom cylinder is tilted backward slightly.

It is because two of the three legs are marginally shorter.

This pair of shorter legs are positioned at the back.

Henceforth, the steel ball or stone ball would certainly roll backward and drop onto the ceramic plate.

The slight slant is not noticeable or apparent to casual observers.

But the performers know which are the two shorter legs, to be placed at the back.

Marking On Bottom Tube

There is a small discreet marking between the two shorter legs.

This is the secret spot to identify the pair of shorter legs.

Steel Ball Rolls From Edge Of The Plate

As explained above, the steel or stone ball rolls out through the cut-out, and falls off the edge of the glass or phone.

It means the steel and stone ball cannot plummet right in the middle of the ceramic plate, as it appears.

Watch carefully at the falling stone ball at 0:39.

In fact it drops down onto the edge of the plate, then it rolls down to the its center.

Whereas in the other demo videos, you cannot see the falling steel ball clearly and accurately.

That scene is a high angle shot, and the front leg of the bottom tube blocks it.

Summing up, this is my view how the steel ball through thick glass trick works.
