Some questions in the process of using the spark machine?
Some Q & A about spark machine: 1) Is it normal for the machine to sound loud? You can hear the motor, it is whistling in the sparks coming out. It is normal for the machine to make some noise while it is running and spewing out sparks. it is unlikely that the machine will be completely silent. 2) The powder I bought is for outdoor use. Is this the same powder that I can use indoors or is there another powder that is only for indoor use? The powder is suitable for indoor and outdoor use. 3) When I put my hand into the fountain about meters away from the spout, the spark is warm, is this normal? Some heat is generated during the spark, so it gets a little hot when touched, but not so hot that it's dangerous to humans. 4) When the powder in the machine is not all used up, do I need to take it out, or can I leave it in the machine until the next time I use it at another show? It is recommended to spray all the fuel as much as possible otherwise the fuel is easy to get wet in the
