Be good. Be very good.
Otherwise you may-
make a tit of yourself
hurt self/others
just further the reputation of fire spinning being something just anyone can do- that doesn;t need appropriate payment or even respect. Cos really if a 'performer' is not good, entertaining etc, why should anyone respect or pay them?
Have a LOT of experience spinning in your backyard/the park or wherever else you practice. There are very many obstacles and distractions that can arise in a performance setting.. especilly, g*d forbid, a bar- where people go to get pissed and even more stupid/reckless than normal. eg people come pick up your stuff while you are spinning. Play at
Fire Breathing. Heckle and try to impress beefhead gf's by making things hard for you. Walk across your space. You may spill fuel or spray it from inadequately spun off toys. Hopelessly tangle or get a burn in public.
All of these things can happen, and experience in your basic skills will help you when things go wrong, as they may well at any time..
Have professional looking costumes that are fire resistant and improve your look as well as enabling you to move well.
Be scrupulous about safety, have excellent equipment in perfect order, and preferably a dedicated safety person or minder who can come with you. Be as smooth as silk in your fuelling/lighting and EXTINGUISHING practices. Do not choreo to burn until your toys are out.. that is a lame look and creates tension. Extinguish them safely while they are still looking good.
Know what you, and your moves, look like while you are spinning by practising in front of a reflecting surface or filming yourself. Beginners often look tragic-- head bent, shoulders hunched, doing nothing in particular and looking nervous about it. Or flinging themselves around in an unfocused way. Use timing, stops, character with your choreo. A performance is a long way from just mucking about.
Then somewhere down the track, when you are really really ready, think about approaching people who have the power to give you a gig.
