SOAP POWERED BOAT
Here is our soap powered boat that Alex has made from a business card.
He cut corners of the card and put soap at the back of the boat. After he
placed the boat onto the water, it scooted across. To try that again, we needed
to rinse out the tray to remove any soap and add fresh water. Soap breaks down
the surface tension of water. As the surface tension is broken up, it creates
enough of a force to push our boat across the surface
