Water balloons are the perfect addition to a hot, July afternoon. Purchase red, white, and blue balloons to keep the game within the theme, and fill them with water. Give kids a wiffleball bat, and pitch the water balloons to them. Of course, the balloons will pop, so there’s no need for them to run around the bases, but you can set up one “base” they have to run to and then make it back to home plate before being tagged.
Saunders suggests an added challenge for a more advanced game: set a garbage can near home plate. Once the child at-bat hits the water balloon, let her run away from the plate to a “base,” while other kids in the “outfield” attempt to throw a tennis ball into the bucket before she returns home.
