How do they work? These hand blasters are ceramic balls coated with potassium chlorate, sulfur, glue, and powdered glass. When the two balls collide, the friction between the sand causes a chemical reaction between the potassium chlorate and the sulfur. This reaction gives off energy in the form of heat and sound.
