All you need is a chopstick and a med rubberband.
and about 15 secs.
This is my first intructable, so go easy on the commets.
Step 1: Just Put Them Together!
(I reccomend wooden chopsticks, in case you lose them)Get the Sticks that you
snap apart, because one end is thick, and the other is narrow.
Step 2: 3,2,1 Blast Off!
DISCLAMER: DO NOT AIM AT ANY LIVING THINGS OR IMPORTANT OBJECTS. IT IS NOT MY FAULT IF ANYTHING GOES WRONG.
There is a very small chance that it would go backwards if you dont do it right, so be careful!
Make sure the rubberband is shaped like a dimond and do it where there are not a lot of people.
