This version of the classic boomerang illusion will “blow your mind”.
You will no longer trust even your own eyes. As you the magician talk about optical illusions, you display two cardboard strips with Cats on them. One Cat has a blue collar the other a red collar. You also show a third strip that is a ruler. With this you prove that the two Cats are the same length. Then explain the optical illusion. Suddenly it is no longer an optical illusion but reality!
To the eyes of the spectators, it appears that the two strips stretch and shrink.
For the climax, the magician proves that the two strips have actually changed size.
The audience will be fooled by this effect, but so will the Magician! This looks so impossible that you will fool yourself every time you demonstrate it.
Oddly I never thought much about the boomerang effect until I saw this! This has taken it several steps further… Amazing. You WILL love this!
