How to Make a BB gun out of a pen
A set of pins are taken, separated and the ink section is discarded. An indented piece of metal pipe is placed and taped at one end of one of the pen shells. A small hole is burned into another pen shell. A bb is placed in the burned hole for testing and let out at one end of the shell. The two shells are taped together. A rubber band is taped to the sides of the shooter shell; in a pull and release manner. Two examples are given of the shooting of the bb from the shooting mechanism section of bb gun.
