Well, I have been spinning fire for about 7 years and I can honestly say the subject of a fire house has never come up. I guess most of us wouldn't have access to one. Not the kind of thing you see at Goodwill or yard sales. With poi, the danger would be having tiny flaming death balls of burning rubber hit your audience. Spend the 20 bucks or so and get you some. It would be worth it just for the peace of mind. Use the kevlar hose to make some sort of fire sculpture. Unifire has a flaming heart that we use at weddings and such. Her is the link www.dube.com
Company owned by Brian Dube who was a reknowned juggler. They are known for quality. I bought my juggling torches and knives and shitloads of kevlar from them over the years. They are on the east coast too so there is a quicker turnaround for stuff ordered. Cool. We will have some spin jams at the house here in the pirate cove and I look forward to seeing you there.
