my friend once knocked a lense out of my glasses with this
while I was still wearing them (This is a mod to thiswith straws)

You'll need a(n);
scotch tape,
two small straws,
hobby knife or scissors.

cut the bendy part off the straws
then cut one at a 45 degree angle.

flatten the part of the barrel where you wish to put the ammo cartridge and cut a half oval into the side.

trim straws to the desired length and tape together.
when firing you might need to move the straw around a bit to get the bb's moving
