Now that you have both you car and your track set up, its time to begin the fun part. First, string the two wires through the pen tubes, and attach them securely to each side. They need to be really tight, or the car will veer off the board as shown below. you should manually push the car through the track, making sure that it flags each photo-gate.
Next you need to insert the igniter into the back of the rocket and place the plug in behind it. Next attach the wires to the igniter, and when the Vernier program is on, go ahead and touch the wires to the battery.
