The Salt Water Fuel Cell Giant Arachnoid Kit gives children a change to learn about new forms of clean energy, while building and powering their very own arachnoid toy. Just feed it saltwater and watch it scurry away--after activating the fuel cell module, the toy can operate for about 5-7 hours. This is a great science fair project or birthday present.
