An impossible trick!
Two solid and identical sticks penetrate each other in a cross-shaped tube!
Your spectators will be able to see the physical impossibility within a few centimetres of their eyes!
1- Show two sticks, and insert one in a cross-shaped tube. The spectators can see that the stick fills the tube completely by looking inside the tube.
2- Insert the other stick into the tube, and without any resistance, it passes through the first stick! Both sticks occupy the same space!
3- Remove the sticks, and let the spectators touch them. There is nothing to see, feel or discover!
You can also let various objects (pencils, etc...) penetrate through the first stick, as long as the object in question is in the tube.
That's easy to do.
