## Step 2: Make the Body

Trim the piece of paper to the length of your pen or dowel as shown in Picture 1.  If you are using a long dowel, you can glue strips together to make them long enough.

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.
This is awesome
For an even more scientific approach, I would connect them to empty plastic bottles as launchers - that makes a fixed volume of air.<br><br>If you drop a known mass from a known height, then that also applies a constant pressure on launch.
As usual kiteman, you've added a valuable lesson. I've been building the little paper rockets for years, but just as a design thing before building the pop bottle rockets. I'm definately going to use your idea this year to up the educational content of the of the exercise. <br>I've also used the air compressor in the shop to launch them. That way we get a constant pressure.
Cool.
That's a great idea too! Wondering now if I could work some physics in- PE=KE. If we can measure the altitude of the rocket, we could calculate its potential energy at apogee, then figure out its velocity at launch...
doing this in class
cool
What does this have to do with education why is it in the education contest
Wow, it sounds like you had a terrible school experience. There are plenty of &quot;real&quot; concepts behind the use of this simple activity: Aerodynamics, Physics, Math, all of which apply DIRECTLY.<br><br>Don't criticize if you don't know what you're talking about...
Never heard of &quot;Rocket Science&quot;?
Lots... I use it in my classroom to teach about Newton's Laws of Motion and as a test bed before we build our pop bottle rockets. There are several more uses for this activity in the classroom- I listed a few of them in the last step.
This is SO awesome I love it
Nice kork!
