Shake and bake meth is a type of meth that’s made by mixing meth ingredients (such as pseudoephedrine, lithium, and ammonia) in a sealed container, usually a soda bottle. When someone shakes the container, a chemical reaction occurs and produces meth.
Since some meth ingredients are explosive, the container may explode if its contents are exposed to the air. An explosion can cause serious burns, blindness, and death.
