I bet you are right Max. Here is something to think about though, these folks are not using household Hydrogen peroxide at 3% concentration. I was wondering if chlorine dioxide would work, its a strong oxidizer and bleaching agent and its a lot safer than strong HP. I use to goof around with "fireworks" and though about using HP and powdered metals, but it was a little too scary for me. If someone is actually thinking of trying this, I'm sure they could find some industrial HP.
