Prototype Rocket

In the episode "Dawn of the Eds" Double-D is working on a rocket project. He finishes his prototype rocket, which Eddy tests. The rocket is shot into the air by a giant spring and then maintains altitude. The prototype however failed when it fell in mid-air. Luckily for Eddy the parachute opened up, slowing his descent. Double-D then stops further development of rockets. His final version probably would've been like the prototype, but larger and an onboard propulsion system. The prototype had a maximum speed of 40 mph and final version should've been able to top out at 60-80 mph.

Here is a list of all items it was built out of:

 * Metal Frame
 * Scrap Metal
 * Steering Wheel
 * Giant Spring
 * Various Other Items
