I've got a simple rocket I could do, or quite a good glider... but, which to do?
I know - I'll combine the two!
See the resulting video in step four.
Step 1: Materials
Step 2: The fuselage
Make sure it's snug, but not so tight that it can't slip off the straw.
Fold the end of the tube over and tape it. The folded end of the tube will be the front of the Huffin' Hoopster.
Step 3: The wings.
You need two rectangular strips of paper. The exact dimensions don't matter at this point, but one should be shorter and narrower than the other.
Roll both strips into hoops (so Hoopster) and fix with a small piece of tape.
Step 4: Construction and launch.
Slip the Huffin' Hoopster back onto the straw, put the straw to your lips, point the HH skyward and blow.
This slightly revised version of the video is ve2vfd's fault...
