•disposable water bottle
•somethin' to shoot
Step 1: Cut the bottle
Step 2: Make it
When you have it cut, take the big bottom piece and pull it over the back of the mouth piece so that it is slightly overlapping the swirly lines.
After that, you take the middle piece, and roll it into a circle, like a small rubber band, and put it on the balloon right below the swirly lines.
Do the same with the little circle piece.
