Throw pennies into the pool and dive for them for prizes.
Swimming pool Pennies Prizes
Throw a large amount of pennies (depending on the number of kids) into a good size pool. Cover about a third of the pennies with white out and send the children in to dive for them. If a child find a penny with white out, that child gets a prize. Great for all ages! Shallow for the youngest and deeper for the older kids.
