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.
Step 3: Cut pipes
2 at 5 feet
1 at 4 feet
4 at 18 inches
Cut one of the 10' lengths in half so that you have two 5' sections.
Then, cut a 4' section from the second one. Cut the remaining 6' section in half and then each of the 3' sections in half.
Step 4: Make a center line
Step 5: Mark locations for misters
Step 6: Drill holes
Step 7: Assemble upright pipes
Step 8: Screw in mister jets
Step 9: Glue base
Step 10: Attach base
Step 11: Try it out
Turn the water on low enough that you get a little spray from all the misters. Check and adjust the direction of the misters to direct the water towards the center.
Turn it on full and look for leaks around the base of the misters. If you find one, you can use a wrap of teflon tape around the base of the mister to stop it.
This project uses 12 misters rated at 10 gallons per hour, for a total of 120 gallons per hour. I don't know how that compares with other water toys, but in an era of increasing water restrictions, getting the most out of the water you do use is a good thing.
Step 12: KidWash times two -- optional chaining
The pictures below show a hose connecting the two, but if you want them right next to one another you can connect them directly together. If you're going this route, make sure the connectors are going to match up before gluing the base to the second unit.
