Science can be really cool. Today let's play with surface tension to make a cool boat that sails using soap as motor.
Start by cutting the boat shape on paper or cardboard.
Then add a drop of liquid soap on the side of the boat.
It will start moving :)
It also works with a leaf.
At the end, the surface tension phenomenon is used to make a rainbow on milk using food coloring.
Hope you enjoyed this simple experiment you can do with kids at home at school or in class.
