I don’t think it is chemistry just added support.
I don’t know….That’s what I was thinking too, but then some pretty good smoke started coming out, on the last example. That would seem to indicate there may be some actual reaction going on.
Being this is the AOMCI, I can see some potential uses for this technique. However, it’s baking soda, so I wonder how it stands up to water……..or gas/oil….
Long live American manufacturing!
