Feather Thru Coin (Quarter) by Roy Kueppers
From the creative minds of Greg Gleason and Roy Kueppers comes this very cool effect.
In front of the spectators eyes, a feather is used to penetrate right thru a quarter. it is clearly seen penetrating as it is pushed thru the coin. the feather can be seen protruding from the back side of the coin as it melts right thru. The complete penetration can be watched right till the last second. the coin can instantly be seen from front and back sides to show that the coin is solid and reveals no possible way for it to have penetrated.
Full video explanation and instructions are included as well as two different colored feathers.
