I spent Sunday afternoon outside filling up approximatly 150 water baloons in rapid sucession for 1 hour so my daughter and her buddy Xavier could chuck them at each other (and me). In the end I got smart and only filled them up a little bit so they'd bounce. This meant that they had to chuck them harder or multiple times before they'd break. Why didn't they have these things when I was a kid? Dollar store item. Way over par in price per enjoyment factor. Best 150 pennies I've ever spent.
