Cylinder Penetration Metal by Mr. Magic - Goocheltruc
A powerful demonstration of Solid-Thru-Solid!! Show a large, hollow brass cylinder with two holes near its closed end. Introduce a smaller solid brass cylinder with two holes in the center. Lastly, show a thin nickel-plated rod which can pass through the holes. Place the smaller cylinder inside the larger one and align the holes to show that the rod can pass through them with ease. Magically, with the rod in place, you are able to have the smaller cylinder fall out from the larger cylinder. Looks impossible, but the audience sees it with their own eyes!
