A fun way for kids to learn about solar power, this grasshopper has no battery but uses solar power from a tiny solar cell to power an entertaining jiggling dance. Quirky antenna sway and eyes jiggle. This toy will keep kids and adults amused for ages and makes a good green choice for a small gift, with no batteries needed. There are also two other toys in this range: a zippy racing car and a scurrying crab.
