In the 1st experiment, what's cool is that the slug fragmented
into 2 equally lethal parts *in mid air* before reaching the
target, *both* fragments subsequently penetrating the solid metal
armor. In the 2nd experiment, what's cool is that upon hitting the
solid metal armor, the slug fragmented into many dozens of molten
metal shrapnel fragments, radiating spectacularly sideways (imagine
if you were standing just beside where the slug hit), as
illustrated by the explosions of the 2 filled soft drink bottles to
the sides of the metal armor. Chemistry note : a "carbide" is a
compound composed of carbon and a more electropositive element (eg.
a metal), and isn't a metal per se, as erroneously stated by the
YouTube video host. But let's not fault him, and appreciate his
video making and sharing efforts instead. He can leave the
Chemistry checks to us... makes you appreciate taking H2 Chemistry
more and more everyday, don't it? ;Þ
