I have seen two methods for making an orange candle. One way is to place a wick into an empty orange peel, pour in beeswax and tada, a candle inside an orange. To me the question of that one isn't "will it work" the question is "will you smell the orange?"
The second method is to pour in oil and use the stem in the orange as a wick. This one seemed a lot more debatable on how well it would work, so I decided to give this one a try first.
You Will Need:
Cut an orange in half. Scoop out the insides while leaving the center core-like them in tact. Pour in kitchen oil (vegetable, olive, etc) just below the stem. Light the stem.
I used a spoon to scoop out the middle and it all came out very easily. I then left it to dry over night.
If this guy could make it work in under 4 minutes, surly so can I.
I grabbed another orange and followed his directions exactly.
I held the lighter to the stem for over a minute and all I got was a burned stem,
and a really cool indent from holding the lighter.
