How to make SOAP BOAT, Surface tension (Urdu & English)

 

SOAP BOAT

Use a piece of soap as the fuel for a cardboard boat. Place a notch in your boat and insert a dab of soap. Put your boat in a tub or basin of water. The boat will sail until the soap reduces the surface tension of all the water in your lake.
