Also known as cold-sparks, these are an innovative alternative to traditional pyrotechnics. Sparkulars work by combining granulated metals and a heating element to produce a non-flammable spark effect. These machines emit a fountain of sparks, which can be controlled in height and duration, and are completely safe to use indoors or outdoors. They produce minimal smoke and residue, making them ideal for use in venues that have strict fire and safety regulations. They are also more environmentally friendly than traditional pyrotechnics, as they produce no hazardous waste or harmful emissions.
