Secret Compartment Pen
This is how to turn a regular pen into a writing secret compartment.
Supplies
- Empty ballpoint pen
- Broken pencil lead
The Only Step
First take the cap off the pen, then you pop/screw off the top and pull out the ink cartridge.
Take the lead and put it in the top of the pen so that it looks like the original.
You can now write a secret message (with the pen) and hide it inside.
You can hide it with some other pens without anyone noticing.
To take it out you can bend a paper clip into a hook and use it to pull the message out.
