There's not much I can say about this other than it's awesome and you should make one. We call it the Bike Wash. Or Kid Wash. Or the Mister (which is a little confusing, but funny). Instructions found here.
Seriously, make one. Especially you N.C. people. Your kids will love it. And so will you. My favorite things about it:
1. It'll keep my boys busy for at least 45 minutes. And a lot of times they want to turn it on a few times a day. This is amazing since they're usually entertained by an activity for about 3 minutes before they want nothing to do with it again for the rest of the day.
2. It's just shooting out a light mist of water (3 on each side and 4 across the top), so you don't get soaked right away, and it also conserves water. I hardly have to turn my hose on at all to get it to work.
3. It came together pretty quickly and the instructions were super easy to follow. I was able to find everything at our local hardware store.
4. I can run through it fully clothed (should I feel the need or per the boys persistent begging) and I hardly get wet. Just super refreshed.
Max thinks you should make one.
It could be the highlight of your summer.
(I hope not. I hope you've got bigger summer plans than that...)
