Step 1: What You Need
1. A LED pen--find these at fundraisers, dollar store (i think), and online. Buy LED pen HERE
2. Large paper clip
3. Some silly putty or something sticky like that.
Step 2: Start Taking Apart the Pen
Unscrew the back section of the pen (see picture #1).
Now you are left with this... (see picture #2).
Now slowly pull out the black capsule with the LED light in it (see picture #3).
