Survival tip: fashion an emergency long-lasting oil lamp from a can of tuna

Although the Osaka earthquake left a trail of havoc in its wake, thankfully there’s been few casualties. There’s no telling when the next natural disaster will strike, however, and having some crucial survival knowledge can sometimes spell the difference between life and death.

In light of the recent earthquake, Japanese Twitter user @Yu__to0911 brought up a useful lifehack that transforms inexpensive cans of tuna into valuable sources of light and heat.

“Many people might know of this but (cans of) tuna can be turned into lamps too.

1. Punch a hole in the center of the lid.

2. Thread some string through the hole and dip it into the oil.

3. Light the string.

Tissue works just as well as string. The tuna can be eaten after being used as a lamp, and it doesn’t hurt for people to learn about this life hack.”

It bears mentioning that the idea of fashioning a makeshift lamp out tuna cans isn’t new, but has recently resurfaced on the Japanese internet due to the Osaka earthquake.

Nevertheless, enlightened Japanese netizens appreciated the tip, while those who already knew of it were glad of the reminder:

“Thanks for this! I’ll try this out tomorrow with a few cans and some string.”

“Oh no! I ate all my canned tuna for lunch today.”

“The aroma of tuna will fill the room though. I’ve tried it before and not only was the tuna heated up, it got rid of the excess oil too.”

“I did this during the Great Hanshin Earthquake. When the oil ran out, the tuna was heated up nicely and it was delicious. You can also heat up water using the fire. It might take a while for cup ramen, but it was quick when I tried it with a cup of water.”

It goes without saying that we humans are at the mercy of a capricious mother nature, but equipping ourselves with techniques like tuna can oil lamps or water bottle showerheads can help increase our odds of survival significantly.
