Caution: do at your own risk!
My lifeguard & swim instructor training DID NOT
include a unit on doing cannonballs...
but every bone in my body screams "whoo hoo"
when given the chance to perform a cannonball!
Take a running start, grab your knees (or not), and jump!!
My older son likes to use the diving board for his fun tricks!
I love the diving board - makes me feel like a kid again!
