Gather 10 empty 2-liter soft drink bottles. Fill each with a few inches of sand or water. Set up
the “pins” in the traditional triangular shape, and take turns bowling with a soccer ball or
something similar. (It would be a good idea to do a trial run, insuring the ball is heavy enough to
push over the pins with a given amount of sand inside.)
