Spin Fire Tornado
You can easily make a fire tornado. But if you don’t want to take the risk, Höfats’ Spin seems to be a great alternative. It uses bioethanol fuel for a nearly smokeless and odorless spinning flame. The optional base and pole provide a variety of display options.
Crowdfunded projects pose a degree of risk for buyers, so be sure to do your research and fully read the seller's detailed description and production plans before plunking down your hard-earned money.
