The refractory beans

From 4 players – 1 handful of dry beans – 4 cups or beakers – 1 straw per player

The players stand in 2 parallel lines. The 1st player in each line kneels down with 2 cups placed in front of him/her. The left cup contains 10 dry beans while the right cup is empty!
At the signal, the players have to transfer the beans of the left cup into the right cup by sucking them up with their straw.
The winner is the player who is the first to succeed. Each team’s points are counted in order to name the winners…
