No, this has nothing to do with textured plaster. Basically, you just squeeze some orange peel towards a flame, and you get more fire. Check it out.
Step 1: Get Orange Peel and a Lighter
-Get an orange, peel it and eat it. Keep the peel. Other citrus fruit will work too.
-Get a lighter, candle, high voltage arc, or other source of ignition.
Step 2: Burn, Baby, Burn!
Wad up some of the orange peel in your hand and squeeze it. Orange oil will come out in a fine mist. Try not to get this into your eyes; it will most likely hurt a lot. It does smell nice, though.
Do this near a flame, and you will see little jets of flame due to the burning oil. If you throw a section of orange peel into a bigger fire, you might see little jets popping off the surface as the cells boil and explode. This will not smell quite so nice, though.
There must be some way of extracting this oil in large quantities, maybe for use in orange-scented floor cleaners, or to add a fruity aroma to burning biodiesel. Just a thought.
