kleberrios Posted January 21, 2018 Posted January 21, 2018 Few or no one knows this, but since I was a child I know that this happens, at the June festivals I would put enormous branches at the fire of St. John, it was the biggest noise, but it fell into oblivion, perhaps I was the only one who kept this in my memory. Today I am beginning a project to chemically extract this highly explosive liquid from the leaves of the Apricó. What will cause this explosion, does anyone have any ideas that can help? https://www.youtube.com/watch?v=ixg-dZptgfo&feature=youtu.be http://www.wikiaves.com.br/flora:abrico-de-praia
OldMarine Posted January 22, 2018 Posted January 22, 2018 It is the sudden rupturing of plant cells containing resin and steam. Not a chemical reaction but merely a physical result of the heat and rapid expansion of gases in the confinement of evergreen tree cells which are naturally reluctant to give up their moisture so they can survive harsh conditions.

But the detail is that before the detonation there is no dilation of the outer membrane, as if gasses or water vapors were expanding, everything occurs in fractions of seconds, whatever the burning is very fast, type Hydrogen and oxygen Do you know another leaf that reacts like this?
OldMarine Posted January 22, 2018 Posted January 22, 2018 Magnolia here does that. Will scare you if you aren't ready for it.
kleberrios Posted January 22, 2018 Author Posted January 22, 2018 Really? Remember magnalium rsrs. When you can make a video of her burning for me to see.
kleberrios Posted January 22, 2018 Author Posted January 22, 2018 I'll gather some tomorrow.I 'll wait for it thanks.
GalFisk Posted January 24, 2018 Posted January 24, 2018 You could probably check if it's a combustion or steam explosion reaction, by heating the leaves to a tempersture above the boiling point of water but below the autoignition point of common fuels. Maybe a heat gun or blowdrier would work.

Maybe a heat gun or blowdrier would work.Looks must be a highly flammable liquid, because not even an oil at its flash point has such a burning speed in such a restricted space, the dry leaf does not work, so this liquid is volatile (but because it does not evaporate through the pores of the plant while the leaf is green?) why when I heated up with the turbo torch gave three exactly equal sequences of detonations? are the cells equidistant from each other?
