Here you can see the orange peel flamethrower in action.

The instructions are the following:

All you need is a candle and some orange peel. First, you have to light the candle. Then fold your orange peel, the shiny, orange side should face the candle. As you squeeze the peel, oils from the peel will squirt into the flame. The oils ignite and produce beautiful sparks in the candle flame. In addition, this experiment smells very nice and Christmassy.

So, go a head and surprise your family and friends with some amazing chemistry at Christmas dinner.
