My friend Tom Darnell's father, Alfred, had been part of the heavy water program for the Manhattan Project and was a Professor of Physics, at UCLA.
He took us to his campus lab one weekend, and demonstrated liquid nitrogen, by immersing a lead bell into the cryogenic, allowing it to 'ring'.
He also did the frozen rubber balloon trick, shattering it into smithereens.
I can't imagine what a pine tree would react like, experiencing something so alien.
Carbon dioxide will probably go down in history as the most addictive substance ever known to man. Willing to sacrifice the very planet he lives on for just another fix. And willing to do anything but live without it, ultimately falling into the abyss of his own making, taking everyone with him.
