Kids will take any excuse to shoot each other with water guns, which I’m pretty sure is the inevitable conclusion to setting up this DIY water gun cup race game.
It’s a super simple project that you probably already have all the materials for, and you can turn it into a science experiment by investigating how to make the cups move more quickly. Try different sized water guns if you have them, standing closer or farther away from the cup, different sized cups, etc.
Do this on a hot day and no one will mind the water gun fight that breaks out after.
