With half of orange, lemon or grapefruit you can make a candle. This kind of candle you can rather use as an interesting interior decoration or maybe for some romantic evening , holidays on the table.
1. First you will need orange, lemon or grapefruit or any other citrus fruit. Now, slice your orange on half and remove the central and leave the white core. That will be are candlestick.
2. In empty half of orange you can now pour the oil. Now our candle is ready and it is time to lit it.
Candle will lit up only if the wick is dry enough.
Now the question is: How long will burn ? Well, honestly, it will burn about ten minutes, and it will extinguish. Also there is an unpleasant smell of oil. But maybe there is an interesting solution for this problem. It depends on what oil you use. Usually sunflower oil is with no smell and with rose color, and when it is burned remains sharp smell. Lavender oil smells nice, but again, the smell is very sharp and when it is burned up it has unpleasant smell. Therefore it is better to use sunflower oil, then add some drops of essential oil and then the smell is pleasant and not so sharp.
Maybe if the core is pre-charred, and then pour the oil, maybe then it will better ? Maybe! Worth a try! Good luck!
