Despite the way it works, this is completely safe and the brief explosion is not able to set any object on fire in front of the nozzle. Even if you put the nozzle near your skin, the blast will only singe hair. The ring itself is unfortunately not particularly powerful, a good one might be able to knock over some Styrofoam cups. The design takes inspiration from various elastic- and explosion-powered vortex ring guns from YouTube, such as Allen Pan’s repulsor.
