This project owes a big debt to the original KidWash instructable by discontinuity. When I saw it I knew right away it was going on the "must build" list for summer. A great combination: simple project, lots of fun for the kids!
I headed down to the PVC section of the local home improvement store to pick up supplies. While browsing the adjacent sections for interesting stuff I noticed the micro-irrigation section and inspiration struck: KidWash with mister jets!
The modification worked great. We turned it on and kids from up and down the block started showing up to help with the testing. It's a lot of fun on foot, but my kids also get a blast out of riding their bikes through it (just like dad at the carwash).

Step 1: Get your parts
2 ten foot lengths of PVC
3 end caps
1 threaded female hose connector (slip fit)
2 elbow joints (90 degree)
2 T connections
1 pack quarter circle mister jets (12 count)
If the option of chaining your KidWash with other water toys interests you, just pick two end caps and add:
1 threaded male hose connector (slip fit)
1 hose cap
Note: you want the PVC hose connectors, not the more expensive metal fittings. Don't give up if they're not with the other PVC fittings, I found them by the sprinkler parts.
The misters used here are from www.mrlandscaper.com, a brand carried by Lowes.
