This video shows you how to collect color to create jailhouse tats. First, set down a metal pan. In that pan, place a blue, plastic, disposable razor. It is best to try and do this outside or in a well ventilated area so you don't breathe in a lot of the fumes. Next, hold a large piece of glass over the burning razor. As you hold the glass you'll see it collects the smoke. Once you feel you have enough, and you should see a large black circle in the middle of the glass, blow out the razor so it stops burning.
