Code Number: 1N22.33
Demo Title: Rocket Car - Little Cart
Condition: Good
Principle: Action & Reaction
Area of Study: Mechanics
Equipment:
Rocket Cart, Sail, Rocket Motors, Engine Igniters and Battery Pack.
Procedure:
Secure a rocket engine into the rocket car with the thumb screw. Insert a electric igniter fuse into the motor and ignite the engine . The car will travel about 30 to 50 feet, depending on the surface its on. (Do this on cement to minimize damage to the floor.)
Next attach the ceramic plate to the car and then observe the car as the motor pushes against the plate as it is attached to the car. The plate may have to be changed periodically as the motors will eventually burn through. B6-0 or C6-0 booster motors work well because they are almost smokeless but others may also be used.
