Block Paradox (2015) by Thomas Pohle

A wonderful fooler which will appeal to any puzzle lover (or fan of unique coin to impossible location effects). I received this without instructions and had absolutely no idea how to “open” the block. You’ll marvel at the precision work involved.

Effect: Briefly, a block is handed out for examination. On the top is a round recess which is too small for a half dollar to fit through. You ask a spectator to try to place the coin into the block. It’s impossible. Have the coin signed. Take a silk and place it over the block. Take the coin under the silk and within ten seconds or so remove the silk and show the signed coin now inside the block!

Or … begin with the coin inside the block and tell the spectator if they can remove it, they can keep it! After their futile attempts, have them sign it so they know there’s no switch involved, and then remove the coin under cover of the silk.
