Coaster-flipping

A family game. While waiting at a restaurant, place a coaster hanging off the edge of the table. Using the back of your fingers, pop the coaster into the air. Catch it before it hits the table. Compete to see who can do this the most times in a row. We eventually learned that this is 'solvable' because with just the right motion you effortlessly lift the coaster into hand. Still fun though.
