I missed the actual edited out part of the post and thought that it contained more than just concentration of the H2O2. I suppose that it's not that bad on its own, but it could be used for some pretty dumb things. One thing we definitely don't want is people posting how to make drugs, explosives, etc. It just doesn't fit the ideals of the forum. If people want to ask questions about these materials, we should answer them if they're of an academic nature, IMHO. Take a look at the thermite thread. There's a lot of bantering in there, but you won't see any references to compositions, how to ignite it, or anything like that.
