Building on the success of OWI’s award inning Salt Water Fuel Cell Car, the second generation appears to be just as dynamic…maybe a little frightening. After activating the fuel cell module with a saltwater mixture, the magnesium metal sheet (3 sheets included) can operate the Spider for about 5-7 continuously.

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 toy. Feed it saltwater and watch it scurry away!
