Flowers & Bugs Birthday Party

Appropriate for: boys aged 6–7 Practically speaking the potato as a battery source isn't ideal. But we're positive they'll love a chance to make a ticking tater, which is one of several earthy experiments in the Green Science Enviro Battery Kit. From a potato powered clock and lemon powered light bulb to a sonic chip powered by soil, all the experiments in this kit come with full instructions (and recommended parental supervision). Unlike other science kits intended for kids, this one has real meat to it.
