The ETEC FX1 Spark Machine is a pyrotechnic effect that is very impressive, thanks to the granules specially developed for the machine, the FX1 Spark Machine can produce spray fountains of up to 5 metres in height. The sparks that emerge from the ETEC machine are cold sparks. Thus, the sparks are completely harmless to flammable materials such as fabric. This means that the ETEC FX1 Spark Machine can be operated almost anywhere without authorisation
