Granddaddy found these new, cool water balloons online (Bunch O Balloons), and you hook them up to the hose, they all fill up simultaneously, and they drop off already tied. It sounded too good to be true, but we ordered some to try. And they worked! To put it mildly, HG enjoyed her first water balloon fight. I see many, many more of these in her future because her daddy enjoyed it just as much as she did!
