Sure, it's supposed to be for kids. But you can't convince me that one of these won't wind up in use at a party where there are no children in sight. Of course, you can let your kids play on it, and if you play with them it gives you a darn fine excuse to get your racing strategy down before your grownup friends come over to play.
What you get is very simple. The "racetrack" measures 16 feet long by 60 inches wide by 12.5 inches high. It even comes with two inflatable body boards for faster sliding! Both tunnels spray water along their length, and the splash pool at the end has a water-filled rim. Basically, whoever wins gets to go headfirst into the water, and whoever loses gets all the backsplash.
Really, that's all there is to it. Hook it up to your garden hose, spread it out, and let the racing commence. At right around $25.00 US, it's affordable summertime fun the whole family can enjoy.
