Even if you choke at the thought of handing over the keys to the Prius, you can get your kid excited about driving electric. Just start small. Really small. The Hydrocar measures a mere 8 inches, but it runs completely clean, with help from a reversible Polymer Electrolyte Membrane fuel cell, and good old H2O. Fuel cell technology could well be the wave of the future, and 14-year-olds are able to understand the chemistry involved. This car is less complicated to build than you might think. But building it is only the tip of the iceberg. The second, more important and difficult part is connecting the fuel cell to the energy source, producing hydrogen gas, and getting the car to move. Does it take patience? Absolutely. But it makes science jump off the page and onto the asphalt. Parents, start your engines! (Discovery Store, $79.95)
