You have an array of spinning tools from which to choose; some fire spinners light up tennis balls and bits of towel, while others spin with a flared staff, chains, whips, fans or even hula hoops.
Anything you want to light on fire and swing through the air should ideally be attached to your spinning implement by something stronger than glue. Your wick is the place on your spinning tool which burns; according to the North American Fire Arts Association safety guidelines, the wick should be connected with a "hard limiting" element, such as screws, wire or a bolts. Homemade wicks made of towel or denim burn consistently but have very short lifespans; the fire spinners at Home of Poi recommend purchasing your wicks from poi retailers and favoring wicks made from fiberglass, metal wire and combinations of other fuel absorbent, heat-tolerating materials.
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.
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, as well 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. 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.
