The Solar Cockroach is a little bug that uses the solar energy to power a vibrating motor. The vibrations from the motor travel down the legs, causing the bug to scoot around. These little vibrating bugs are essential tools for teaching beginning soldering lessons to students and adults of all ages. This project also offers a lesson in solar energy, motion, and vibration. Simply place the completed Solar Cockroach in the sun and watch it vibrate and scoot around!
