Would it be possible and/or probable to achieve combustion by adding a small amount of water to a specified powder mixture?
I've been looking at instructables for the past few months but only recently joined.something that really interested was an instructable about creating fire from a drop of water https://www.instructables.com/id/How-to-Start-Fire-with-Water/
and i thought that that was so cool. But, some of the comments suggested that one of the substances used, NH4, or Ammonium Nitrate, was now illegal. Is there possibly a better way of having that same type of powder that when it comes in contact with water, it will light on fire? If so, please tell me or give me a link to something else that will tell me how to do so (I don't even know if that actually was ammonium nitrate, but that is what the creator said.).
