You should conserve a fire extinguisher handy when you spin conflagration.
Embers spinning originated with the Maori of Fresh Zealand, who training the Craft of heat dancing as one of their traditions. The heat spinners exercise a disparateness of tools, some bonfire related, some safety related, for their daring performances.
Spinning Tool
You carry an array of spinning tools from which to select; some embers spinners flashing up tennis balls and bits of towel, while others spin with a flared staff, chains, whips, fans or yet hula hoops.
Fire safety authorities recommend a smooth filament fire blanket for all human torch fires; human torch fires occur when a person and their clothes have caught on fire. Since you are playing with fire, keep the appropriate safety equipment around in case you are burned.
Fuel
Luxotica, a fire spinning tool retailer, explains on its website that fuel is a subjective spinning element and that you'll probably have to figure out through trial and error which fuel fits your needs best. Camp fuel or white gas releases a white flame and burns cleanly, making it a good option for indoor performances, but evaporates quickly. Kerosene and lamp oil release orange flames and have a more sustained burn, but this burn is also smoky, so this mix is best for outdoor use.
Safety Materials
In case your flame gets out of your control, always have a class A, B and C fire extinguisher, which should take care of all ranges of fires, also as a first aid kit that contains burn first aid items. Never spin alone; always spin with a friend who can tell you if you have set yourself on fire.
