Reminds me of a time I thought I would be creative and do some chocolate bowls like I say on food tv. You take a blown up balloon and dip it in melted chocolate and then sit is aside to harden. Once hardened you pop the balloon and you are left with a nice bowl of chocolate you can fill with ice cream, fruit, etc.
Well as I learned, you don't want to use balloons that are close to their max size and you also want to use chocolate that is just barely melted and not very hot. We were still cleaning chocolate off the walls, cabinets and ceiling 3 years after this incident when we were moving out.
