It won’t matter the age, every ‘kid’ loves doing
cannonballs. This is just one way to legitimize it. Have the group
line up. The goal here is to get the highest splash using a cannonball
(you be the judge). The cannonball group lines up behind a diving
board, starting blocks, and pool deck and gets as many chances as
you like to get into first place. Insure lifeguards and pool management
are in agreement with this activity before you commence.
Variations: Try the
opposite... the person who can enter the water with the smallest splash.
