I didnt know that much about olive oil and I used it a lot when I was able to cook, and would buy a big bottle of it. Well, after I was unable to cook, it went bad and I couldnt bring myself to throw away the oil, so I looked it up and found out you can make little lights that dont smoke (so they say). You take a small glass oven safe bowl like a custard dish and put the oil in it and put one cotton ball in it and dip it so its all wet. Then pull a bit of the cotton ball up (squeezing off the excess oil for that part) and it will be the wick. Light it and wa-la...
