So, a tuna can lamp is simply punching a small hole in the top of the tuna can, inserting a wick and lighting. For this lamp I used a cotton ball that I corded out a couple inches. You can use cotton string or any other cotton material, a piece of rag for instance.
1: Poke hole
2: Insert wick
3: Light wick
4: Enjoy light
Added bonus: You can still eat the tuna after it has burned out.
