Tattoo ink can be made using soot as the coloring agent. This method is commonly-used in prisons and other places where there isn't access to regular ink. Create ink by capturing the soot of a burning substance and mixing it with a few other ingredients.

Burn something that produces heavy black smoke, such as plastic, baby oil or hair grease.

Place a trap above the burning substance to catch the smoke. This can be soda can cut in half using tin snips, a piece of aluminum foil or anything that will not melt. Allow the substance to burn for five to 10 minutes until you collect a large amount of soot.

Collect the soot into a cup and add 1/2 tsp. rubbing alcohol and a few drops of water.

Stir thoroughly using a spoon until a paste is formed. If there is any remaining powder, add a few more drops of water and mix again.

Add a drop of shampoo to thicken the mixture. Mix thoroughly, but avoid mixing too vigorously as that can cause bubbles to form.

Warning

This ink is unsanitary and may cause infection if used for tattooing.
