1. Giant straw
2. small drinking straws
Step 2: Tape straws together....
Set two small straws by each other (side by side) and tape. Tape it at the top, in the middle, and at the bottom. Do the same for the other two small straws.
Step 3: Put it all together..
Now attach the straw bundles (2 the straws of 2) to the big straw with tape. If you want you can mark the end (or the beginning) with foil (or and other thing).
Step 4: Test it out!
Take a SMALL bit of the paper and ball it up. Put it in the beginning of your gun, then blow on the SAME end for maximum force! :D If it gets stuck turn the gun to the opposite side with the paper then blow on that side.
