The U-Shape Triple Water Trough is a large water activity that can entertain large numbers of small children with its cascading streams of water. The water starts at the top trough, where you can attach a garden hose to start the waterfall that eventually travels all the way to the drain at the end of the third trough. Beneath that, a simple basin can be used to collect the water. Kids will love following toy boats or rubber duckies as they float downstream. The water can also be used to teach early science lessons about water and buoyancy.
