PHYSICS PROJECT REPORT ON BALOON BOAT

You will need:

  • 1 x thick sponge
  • 1 x balloon
  • 1 x piece of 2cm clear plastic tubing (available at Bunnings)
  • craft knife
  • scissors

Use the scissors to cut a pointed end to the sponge to make the bow of your boat.

Now in the stern of the boat, use the craft knife to make a small slit. Feed the plastic tubing through the slit so that it sits halfway.

Blow up your balloon and let the air out to make the balloon nice and stretchy.

Now slip the end of your balloon over the top of the plastic tubing – the bit sticking through to the top of the boat.

Fill up the bathtub and blow the balloon up by placing your mouth over the lower part of the plastic tube – the bit sticking below the boat’s ‘hull’. Place a finger over the end of the tube to stop the air coming out straight away.

Put your boat into the water and remove your finger, the rush of air from the deflating balloon should propel your boat across the bath.

You’ll have to squeeze the water out of the sponge each time you launch your boat.
