You can use the straw or the pump to launch it. When using the straw, push it in the barrel until it is secure. Then blow hard until it pops. If you c...
What is easy to make, fun to shoot, and takes only 10 minutes of your time? Pneumatic Paper Rockets!
These take only 5-10 minutes to make, but provide a lot of fun. All you need is an index card, tissue, and tape. To launch you need a bike pump with a nozzle shaped like this >. This nozzle = and this one --- wont work.
Wrap the paper around the straw. Wrap it just loose enough for the straw to slip out.
Step 3: Tape
Wrap tape all around the barrel, then let the straw fall out.
Step 4: Attach Fins
Cut 3 pieces of tape (picture 1)
Then fold them (picture 2)
And cut (picture 3)
Then attach it to the barrel (picture 4)
Repeat for all 3 pieces of tape.
Step 5: Cover top
Your rocket should now look like picture 1.
Put a piece of tape over the top, so it looks like picture 2.
Step 6: Create inner weight
Take a piece of tissue (picture 1), and crumple it into a small ball (picture 2). Now insert the tissue into the straw (picture 3). Take some glue (hot glue or Elmer's glue), and put a little spot on the top of the tissue (picture 4). Now stick the straw all the way into the barrel (picture 5).
WARNING: HOT GLUE IS HOT! IT CAN BURN, SO BE CAREFUL.
Step 7: Attach outer weight
Take another piece of tissue, and crumple it up. put this on a piece of tape, as shown in picture 1. Then put this on the top of the barrel (picture 2). You might want to seal it with some more tape. Picture 3 shows the rocket thus far.
Step 8: Finishing the rocket
Now, you just have to wait until the glue dries. Then you can pull the straw out. If it does not come out, just blow in the straw.
