In this Instructable i will show you how to make a counterfeit money pen like the ones you can buy at like Walgreen's.
Step 1: Materials
For this pen you will need:
1. A Crayola Color Explosion marker or any marker that doesn't have color( dry markers don't work)like invisible ink pens. If you don't have one, get a highlighter, dissect it and rinse out the reservoir.
2. Iodine tincture first aid antiseptic, you can get this at any drug store
3. a syringe and needle ( be careful!) you can get this online or by bribing your doctor
4.And of course, MONEY
Step 2: IONDINE
Now you need to syringe about 2-3 mL. of iodine into the syringe. it may take a little while, so be patient!
Step 3: INJECTION
Now just syringe the iodine into the color explosion pen nice and slowly. When you can see iodine ooze out of the marker tip, wait for it to get absorbed and repeat.
Step 4: Done!!
Now get some cash and make a little X. if it turns amber brown it real. if it turns black, well your screwed!
