this is all of the stuff you are going to need to make this Instructable.
2 bic pens(doesn't matter what color)
duck tape(this is the best tape to use)
this is all you need!!! simple
Step 2: Pulling the pen apart
Now take off the caps, and pull the whole top of the pen from the grip. Make sure there is nothing in the tube for the next step.
Step 3: Cutting off the ends
Now you have to cut off the ends of the tube, so both sides are open. You are almost done
Step 4: FINAL STEP!!!!!!!!!!!!!
Now all you have to do is put duck tape around it, and wala your done. The bottom one is the one I made earlier so you could see that you can make it different sizes. they are both fine and it doesn't really matter I think. You just put a piece of patter in your mouth then put it at the end of the tube, then blow!!!
