For a fundraiser for geology club, my friend and I decorated cupcakes. Clearly we didn't follow any decoration standards, but we had fun with it!
The best part was when my friend ate one of the cupcakes I had decorated with just pure food dye. It turned her whole mouth (teeth/ tongue/ gums/ etc.) blue. She kept saying "you're lucky it was a friend who bought that cupcake and not a stranger!" What a good sport :)
