There many different firework fountain machines on the market, but one of the most interesting types of this special light effect is a model that's suitable for indoor use and doesn't require a permit. These machines are completely safe as they provide their sparks using a special powder that's heated inside the unit until it blasts out cold and impressive sparks! They're not flammable and there's no smoke either. Although they produce authentic looking firework effects, they're not a fire hazard making them perfect for use at any production, gig, party or show.
