How to Make a Soda-Straw Rocket
1. Carefully cut out the rectangle. This will be the body tube of the rocket. Wrap the rectangle around a pencil length-wise
and tape the rectangle so that it forms a tube.
2. Carefully cut out the two fin units. Align the rectangle that extends between the two fins with the end of your body tube
and tape it to the body tube. Nothing should stick out past the body tube! Do the same thing for the other fin unit but tape
it on the other side of the pencil so you have a "fin sandwich."
3. Bend the one fin on each fin unit 90 degress so each fin is at a right angle to its neighbor. When you look along the back
of the rocket, the fins should form a "+" mark.
4. Using the sharpened end of your pencil, twist the top of the body tube into a nose cone. Measure your nose cone from its
base to its tip and record the length on your Data Log and on the rocket itself. (For the Data Log, create a chart on a piece
of paper with columns labeled Rocket Length and Distance Traveled. For every attempt, fill in the log.)
5. Remove the pencil and replace it with a soda straw. Blow into the straw to launch your rocket! Record the distance it
travels on your Data Log.
