Have physics fun with five amazing rubber band powered models! Crafted from ultralight plastic and bamboo parts, you can build a helicopter, fan boat, airplane, car, and catamaran. Discover how elastic material stores and releases energy to bring these models to life.

To use these rubber band racers, first, assemble the models using the provided ultralight plastic and bamboo parts. You can build a helicopter, fan boat, airplane, car, and catamaran. Then, wind up the rubber band to store energy. When you release it, the stored energy will be released and make the model move. Make sure to handle the parts carefully to avoid breakage. After use, store the models in a dry place. If any parts get dirty, you can gently clean them with a soft cloth. Have fun playing with your rubber band racers!
