Solar Energy Powered Cockroach Toy Gift

When it exposed to sunlight, it can start its mini-engine by shaking itself, so no batteries needed, powered by sunlight, it will shake itself seemingly forward or backward, spinning around as it is looking for food. Both specially designed and eco-friendly, this product is also an excellent teaching aid to provide students with some basic knowledge about solar energy.
No batteries required! Power by the sun (or strong indoor lights), this little bugger will scuttle around, scaring the weak-willed and impressing the scientists.
