Instructions
Place your slip and slide on a hill, with the finish line at the bottom. Water runs downhill; putting the slide on a hill helps slide speed and water distribution.
Lock the oscillating sprinkler so that it sprays in one direction. Most oscillating sprinklers include a lock function for watering one specific part of a yard.
Connect the sprinkler to a garden hose and run the other end of the hose to an outdoor faucet.
Place the sprinkler next to the slip and slide and turn on the water. Position the sprinkler so that it evenly coats the length of the slide. If it doesn't cover the entire length, place it near the top and let the water run down.
