Hijack alert!! I found this article earlier today. These folks won $5000 for creating edible soy candles. Purdue students put the 'happy' back into birthday candles WEST LAFAYETTE, Ind. -- Now you can have your cake and eat the candles, too, thanks to three Purdue University students who have created an edible birthday cake candle that uses hydrogenated soybean oil instead of petroleum-based paraffin. The peppermint-flavored candles don't drip and have a slightly shorter flame height. Christened "Flavor Favors" by their student inventors, the soy-based candles burn an average 25 seconds longer than commercial candles. The candles took first place in a universitywide undergraduate student competition sponsored by Purdue's Department of Agronomy and the Indiana Soybean Development Council. Inventors Amy Khal of Iowa City, Iowa , Rahul Nair of Jackson, Miss., and Adam Watkins of Goshen, Ind., all students in the Department of Agricultural and Biological Engineering, split a $5,000 prize. The composition of the candles is 83 percent hydrogenated soybean oil; 16 percent glycerol, a sweet emulsifier; about 1 percent coloring; and a bit of concentrated peppermint oil for flavoring. A combination of fully and partially hydrogenated soybean oil gives the blue, red and yellow candles form and texture; the glycerol makes the candles slightly softer and easier to chew. The peppermint oil could be replaced by other flavors as desired, Khal said. Watkins, who was the designated candle eater for the team, says he wants to continue work on replacing the cotton wick with something tastier.
