Okay, these are not card tricks. BUT you will need a deck of cards to perform them! First, can you build a house of cards sturdy enough to balance a wine glass full of water? Sounds impossible, but there is a solution! Next, balance a quarter on a card on your index finger. See if you can remove the card from under the quarter (while keeping the quarter balanced on the tip of your finger!) by touching only one edge of the card.
