Hands-On Wednesday: Soap Powered Boat

STEM Hands On

Soap Powered Boat

Create your own soap-powered boat to travel across the water’s surface. Soap is a surfactant, which means it breaks up the surface tension of water. When you put soap on the lightweight boat, the soap breaks up the surface tension on the water with enough force to move the boat forward. Now try out different kinds of soap to see which soap makes the boat go faster!
