Crossing the river

From 4 players – equipment: 2 phone books – 1 stopwatch or a timer (optional)

Delimit a space representing the river to cross. A few metres will do. To cross the river, place a “brick” (a phone book) in front of the other and put a foot on each brick.
Then, balancing on the brick ahead, grab the brick behind and place it in front of the first brick in order to make another step.
Start again as many times as necessary to cross the river without falling in the water!
