On first note, you might see very many copies of this experiment, due to our class having to individually post one. Moving on, This experiment was dangerous during our trial runs, so proper protection will be essential. Another thing is that this experiment leaves a big mess.

## Step 1: Build a Secure Track

Usually a 2X4 in. width and depth of the wood is sufficient, however make sure the length is a Approximately 4.8 Meters in length, the reason being is that the Vernier equipment (mainly photogates) that we used only operate in the Metric system, and 4.8 Meters is Perfect for 5 Photogates to collect enough data. Use Metal 'L' brackets as blast shields for the front and end of the track. It is also preferable if you use Metal Wires that the car can run along so it won't steer off track.

## Step 2: Construct the Car

When you attach the Rocket Engine to the top of the car, first add straws to the sides so the tracks metal wires can go through them and keep the car on the track. Then Secure it, Electrical Tape as well as regular Duct Tape works well. Then when all the parts are secured, add the igniter and the plug to the back of the Rocket Engine.

## Step 3: Launch (The Dangerous Part)

Put the Car on the track on attach the metal wires through the tubes. Once that is done, collect the data a few seconds before you actually launch the car.

## Step 4: Collect the Data (The Safe Part)

Once the car is done fireing, or just completly run off the track, view the Vernier Data, this will tell if you succeeded or ultimatly Failed.

DANG IT! I JUST LOST THE GAME!
