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.

Step 1: GET a PEN LIKE THIS

Needs to have two holes to release the guts.

Step 2: EMPTY IT

Take out the guts

Step 3: ADD MORE SPRINGS TO THE TIP

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

Step 4: PUT IT BACK TOGETHER

Put all the stuff back in the body.

Step 5: FIRE AWAY

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.
