Okay so you might have to have a little imagination, and be quite frugal to get your head around this one. Imagine, you want to eat an orange, but you don't want to eat it in the dark. Here is an appealing way (pun intended) to have both.

All you need for this is a big orange and some olive oil. Seems pretty simple, but I am sure I could make a mess out of it. But won't the family be impressed when they come over for a candle light Thanksgiving dinner! If you don't eat oranges, I don't think this would save you money, but the house will smell good! Plus it should burn for hours.
