Tuna is a great source of protein as well as omega-3 fatty acids. Canned tuna can last a long time, is easy to store and is relatively cheap, so it’s no surprise tuna is a great food to stock up on. However, tuna can serve you more than just a meal.
Tuna can easily be made into a number of dishes, eaten straight from the can or made into a quick sandwich. After all, efficiency is vital in a survival situation. However, tuna does contain mercury, a toxic metal, and should be eaten in moderation.
As the video shows, you can easily turn a can of tuna into a candle. Of course, it needs to be the tuna that’s canned with oil instead of water. The improvised light source can last for 2 to 3 hours. Not only that, but the tuna is still good to eat afterward!
If you don’t have any newspaper or toilet paper around, a tampon string can also be used as a wick in the tuna can light. Check out other uses for tampons aside from their intended purpose.
