Tuna can oil lamp.

Here's a nifty little video I found elsewhere. Be sure to buy your canned tuna packed in OIL. Gotta love multi-use food!
Hmmm..... wonder if it would work with canned sardines!?

I'll bet fish oil stinks like hell.
It's not something I would advise testing in the house,thats for sure.

The priciple of how it works is the important thing

The same basic methodology using an empty tuna can and using olive oil or vegetable oil as the combustible fuel would work just the same....it may be a good final use for cooking oil that is no longer useable for deep frying food.

 

Been saving my used cooking oil for exactly that purpose. Just pass it through a coffee filter to get out the 'chunks'.......
