Yes, it's a sprinkler. But it's also a jumping game, because you can set it to four different heights. The idea is for your kids to jump over the arms of the sprinkler without getting whacked by them. The higher you set it, the higher they have to jump. It also shoots water out the top, so you can water your lawn at the same time. Neat, huh?
Because I'm me, I can also see the possibilities for this during an adult backyard party. I'm sure we all have that one friend (sometimes more than one) who thinks they are the cat's pajamas when it comes to party athletics after a few cocktails. So get out the Water Jumper, set it to its highest level, and let the games begin! You could probably even turn it into a drinking game if you wanted, where if you get whacked in the ankles you have to drink. Or something. It's really made for kids, but I tend to think outside the box.
If you'd like to pick one of these up, it'll cost you approximately $26.00 US.
