When the sun shines on the solar panel at the back of the grasshopper, it makes electricity, and its micro vibration motor makes it shake its body as if it's ready to prey on something. It's novel and unique, also it's a good demonstration of solar power on a small and cute scale, a wonderful enlightenment for students' solar energy concept teaching as well.
