Feichao 20m Distance Rubber Band Power Car Model DIY Educational Science Kits Kids Experiment Fun Physics Toys

Name: Rubber band powered trolley
Size: Length and width about: 15.5 * 10CM
Product introduction: The rubber band moving car is to use the elasticity of the rubber band to twist the two strands of the rubber band together to deform the rubber band. The elastic potential energy is converted into kinetic energy when the hand is released, and the car will move forward.
The purpose of the experiment: 1. Improve the hands-on ability by making a rubber band powered car for novices.
2. Understand the process of transforming the potential energy into the kinetic energy of the car through the release of the rubber band.
