4M Bottle Catamaran Green Science Kit

Build your own catamaran boat and then watch it skim across the water on its pop bottle floats pushed by its spinning propeller. Supports the green science outlook by reusing two of the millions of plastic drink bottles that are thrown away every day.

Add two 1-liter bottles to the contents of this kit and make a 10" x 9 1/4" catamaran. Launch it in the pool and watch it go!

Requires 2 x AAA batteries (not included)
