Fuel Cells Solarbotics (get a few extras,
as these are the first things
Fuel Cell Car Kit (Item# KT- to burn out)
FUELCCK from  Twp NPN 3904 transistors
www.hometrainingtools.com). This from Radio Shack or
kit is a bit expensive, but if you Solarbotics (get a few extras,
want to build a car that runs as these are the first things
entirely from sunlight and water, to burn out)
this is the one you want to get.  Two voltage triggers from
The company that makes this Solarbotics (get the 1380-G
particular model also sells the or J or N)
conversion kits for (real!) cars.  Two 37x33mm solar cells
Great starter kit for kids interested from Solarbotics (we won't
in fuel cell technology - after kids be using the circuit on the
get the hang of how it works, they back - just the solar cell)
can up the power and perhaps use  Paper clips (a few of each:
it on a go-cart? small and large)
 Hot glue gun, soldering iron
Beam Robots with solder, electrical tape
 Pliers, wire cutters, diagonal
 Tiny eccentric motor from cutters (if you have them)
Radio Shack or Solorbotics
(you can also rip one out of Optional Beam Robots: After
an old cell phone) you've built the BEAM robots
 Vibrating disk motor from above, you can move onto more
Radio Shack or Solarbotics advanced designs. Here's the
(you can also rip one out of parts you'll need for them:
an old cell phone)
 Two 2.2k-Ohm resistors from  Solar Roller
Radio Shack or Solarbotics  Trimet
 Six 4700 μf electrolysitc  Miniball
capacitors
 Two PNP 3906 transistors
