Powered by a rubber band, this
solid wooden boat zips across the water. And it is so easy to use. Just wind up
the paddle wheel toward the back of the boat, place it in the water and let go.
Watch it zoom across the bathtub or cruise in open water. If the rubber band
breaks simply replace it with another one included in the box. This classic
science toy will last forever!

These boats run on energy stored
in the rubber band attached to the paddle wheel. As you wind the paddle wheel,
the attached rubber band also winds storing muscle energy. The more you wind the
more energy is stored (be careful not to over wind or the rubber band could
snap). When released the rubber band unwinds, in-turn causing the paddle wheel
to rotate and the boat to move. This is an example of repeatable mechanical deformation (energy is
stored by bending or deforming the rubber and released when the rubber returns
to its original shape).
and sinking. The boat floats because the wood it is made from is lighter
(or less dense) than the surrounding water.
