A Pen Blowgun and Ammo Case.

This is how you use two pens and a few beads to make a blowgun and ammo case.

Remove both pens insides: the ink cartridge and spring. And put them back together, but leave one end of one pen off.

Find beads that fit in both the pens snugly but not tight.

Now insert a bead in the pen with no end and blow through the pen. Do Not Aim At People Or Animals!! Use the other pen case to store your ammo.
