EEEYEEEWWW~!!!! "Eu de Baby Vomit"!!! (of course, spoken like Pepe le Pew)
And, making orange oil is pretty easy. What I do is put a ton of orange peels (10+ oranges) into a large stock pot full of water. Throw in a cinnamon stick and turn onto low low low. I've also done this in the crockpot too. After about 2-3 hours, the water's pretty evaporated out PLUS the house smells wonderful. You could also buy orange oil at health food places, but I like making my own.
