It's just another one of those things that does the rounds every so often. In the back when a guy called Rudiger Nehberg had his name linked to it for some mysterious reason. If you want to dig about look for “Rudiger Roll”. If you just want the lazy version 'tube up “boggycreekbeast” 'cos he's been playing with this for a while and sticking the vids up. You can use all sorts for the accelerant. Dry shite ground up works, as does the black stuff you can find in batteries. Even bicarb of soda works. Rust, ground up shells or bone, all sorts. Have a go in leaves or plants stalks, or even a bunch of hairy string.
A homeless bloke showed me how to do it decades ago with stuff he grabbed out of a public bin.
