27. Peanuts can be used to make dynamite but please don't try to make. Obviously, peanuts are a tasty snack—as long as you're not allergic to them, that is. But did you know they can also be used to make dynamite? When extracted, peanut oil can be turned into glycerol, which can then make nitroglycerine, an unstable explosive substance used in dynamite. In a safer state, glycerol is also used for soaps, creams, and various food products.
