I used 45% infill so the middle piece has a little weight to it.

You will need 5 quarters. Don't let them see #5 until the very end!

The only slight of hand you will need is to palm the 5th quarter in your left hand (the hand you dump the quarters into) and don't let anyone see that quarter on the first dump. You don't need to worry about the next dumps and be careful dumping out the coins as you will always be leaving one in there and you don't want it to slip out during the coin dump into your hand.

Enjoy!
