Ballistic Pen

It may look just like an ordinary pen but it may just save your life one day. This was something I made in middle school and its been with me since.

Needs to have two holes to release the guts.

Take out the guts

Add one cause if it had three it wouldn't let you use the pen part.

Put all the stuff back in the body.

Now it's a spring loaded shooter. just push the little trigger on the second hole. Best part is you can still use it as a normal pen.
