      Boats Activity
      307 Views . 7 months ago

Surface tension allows the cardboard boat to float on top of the water. Adding soap disrupts the arrangement of the water molecules. The water molecules near the detergent are attracted to the detergent as well as to other water molecules, so the surface tension of the water behind the boat decreases.
