Step 1: Gather Supplies
Strip of paper about 2" wide and as long as you want to make it
Pen or dowel slightly thicker than the straw
Step 2: Make the Body
Roll the paper around the pen tightly as shown in Picture 2, and then put glue along the last edge of the strip. Roll it over a few times to push the edge down tight so the glue will stick!
Slide the tube off of the pen.
Make the Nose Cone by flattening a part of the top and folding about 1/4" of it over as shown in Picture 4. Glue it down.
That was easy! Lets make some fins.
Step 3: Make the Fins
Once you have all of the fins cut out (remember, try different styles, sizes, and numbers on different rockets!), we can glue them on. There are two ways to do this. The easiest is to just put a strip of glue down the edge of a fin as shown in Picture 2 and then glue it flat to the side of the body as shown in Picture 3. The other way to do it would be bend the edge of the fin, creating a tab to put glue on. To me, its just an extra unnecessary step, but its your rocket!
Continue attaching the fins, trying to make them as evenly spaced as possible. Also try to get them as parallel to the body as possible for straight flight.
Step 4: Launch!
Step 5: Ideas for Classroom Use.
Demonstrating Newton's Law's- action/reaction of rocket when launched, momentum & inertia, etc.
Center of Pressure vs. Center of Gravity- attach fins to top of rocket instead of bottom and compare flight characteristics
Physics / Trajectory- set up a box or can and have students try to get rocket in the "goal"- tip the box on its side so rockets have to enter from the side (flat trajectory), then tip box up so rockets have to come in from the top (high trajectory)
Thrust and drag- compare large fins to small fins, soft blow to hard blow (or even use an air hose to REALLY launch them across the room...)
