Thermite in a beaker/glass/mob/and that thingie nobody knows

[Tteckk]

Say Mr ankleidontgivafuk makes some thermite and says "Hey! Im a traitor/round start suicider, Im going to get a welder and ignite this in a nice controlled 1x1 blaze!" what Mr ankleidontgivafuk doesn't know, is that using a welder or any igniting tool on a beaker of thermite doesn't work!
Finding this out on his own turned him psychotic, he threw himself into space as he gasped YOLO.

For the future children of Mr ankleidontgivafuk: I suggest this be added. improvised thermite mines sound fun.
