It seems to be very old topic, but good results !

Demonstration effect : http://www.kevinparkerproductions.com/descent.wmv

This is a visual coin-through-glass that does not require magnets, wires, strings, threads, special coins, or special tables. The magician borrows a coin, drops it in the middle of the table, and pushes it through, the coin visibly landing in his empty hand underneath the table. The coin can even be signed, and the coin, with signature on it, is clearly seen in the magician's hand after it falls through the table. With just your bare hands and a coin, you We are achieving this.

use any kind of coin
no trick tables needed
different objects can be used; candy, paperclips, etc.
Easy to perform
