Ultra Capacitor Car

UltraCapacitor Car: Build a high performance electric car that runs without a battery! The kit contains a 7 farad ultracapacitor, motor, wires, car base, car body, decals, wheels, axles, gears, washers and battery band. Using an ultracapacitor instead of a battery, your car can accelerate almost instantly to race-car speeds. Ultra capacitors can be charged very quickly and be recharged 100,000s of times without wearing out. The energy density of ultracapacitors, also called supercapacitors, may be approaching that of lithium batteries. Stay tuned.

When fully charged these cars are high speed and will even bounce off walls. To hold them together under such conditions, you might want to apply a strong glue, not provided in the kit.
