Educational toys are at the top of my list, fun toys with a meaning are a great way to teach children any message. What a better way to teach children the efficiency of solar power than this solar-powered helicopter kit. They get to assemble the helicopter and then watch it work before their eyes! The kit is made from laser cut plywood and is very easy to assemble without glue. The solar panel in the blades is powered by daylight causing the blades to turn. The solar-powered helicopter kit is available to buy from Sourcing Planet, price range between £9 and £15.
