Step 1: Materials
Step 2: Making the rocket car
Step 3: Create track
Now you need to make the track. You can do it any way you feel like, but this is how we made it our first try. This way got the job done, but it didn't work very well. We put a long 2x4 as the track. We attached L brackets at each end and run a wire through each bracket along the track. We also put photogates along the track to gather data.
Step 4: Launching rocket car
Attach the car to the track by putting the wire through the pen on the car. Put the igniter in the rocket and we ran the wire to a car battery. We touched the wires to the car battery and the rocket car took off and hit the end. With this track though, the car would fly off the track and break the wire or fly around the track.
