You don't need to be a rocket scientist to launch this cool new Water Rocket Sprinkler into the air, you just need a hot summer day, a garden hose, and good water pressure. This little rocket ship rises high off it's water jet launchpad and hangs suspended in mid-air as it rotates and sprays water 360 degrees all around it. Just place it over the jet, slowly turn on the garden hose, and watch as it soars upwards... the better your water pressure, the higher it can fly. As it floats in the air, kids (or you) can run around it to cool off, try to shoot it down with squirt guns, or just attempt to run through the hydro propulsion without it falling. If you need more precise launch control, add this Water Flow Lever to your hose line. Check out the video below to see it in action. Cool huh?
