I have this pair of fyrefly juggling balls made for juggling with fire, the thing is, they are the ones from when they were made of metal, and I can't find any instructions on how to handle this version. I tried juggling them once, and they got so hot that it kept burning my hands, it was a chaotic ordeal with fire going everywhere. Is there anyone who tried and maybe mastered these, or have some old material on how to? I can't seem to figure out smart ways of handling them.
