Is Dr. Pepper flammable?
Dr Pepper is a soft drink. Mostly water with some sugar or HFCS (high fructose corn syrup) dissolved in it. Small amount of carbon dioxide, flavor, color and perhaps a preservative. There is no way it could be flammable. Even with some alcohol it would take quite a bit to allow it to support a flame. Just think about whiskey or brandy which doesn’t burn. Somebody is pulling your leg.
