It is very easy to make and will take about 3 minutes.
Step 1: Materials
-Normal BIC pen (not a click pen)
-Tape, I used duct tape but electrical tape may be better.
- Wide rubber band (this will shoot the ink tube)
Step 2: Take Apart the Pen
(you may need to pull the top off using the scissors.)
Step 3: Making the "Pocket Rocket"
- place it on the small part from the pen and tape it on (see pictures 2 and 3)
