Ask 3-6 persons to participate in this game. Each of them is given 2 paper (plastic) glasses filled with water. In front of each player on the floor there are 5 cardboard circles which are situated at the equal distance from each other. The players' task is to get to the finish line jumping from one circle to another. The player who has water in his/her glasses at the end of the game is the winner. To be more accurate and to make the game funnier you may measure the water in the glasses by the measuring glass.
