I did check thallium pretty toxic definitely don't want to lick that, but gallium on the other might be ok. Plus you could probably rob a a bank with gallium. Gallium is my favorite element
Gallium is absorbed by other metals. Even steel. And it makes them crumble. You could walk up to a door, squirt some gallium into the lock and the lock would fall apart.
Ok so I've re checked. It is completely possible that the videos I've seen only use Aluminium locks. There are people who claim it does destroy steel and people who say it doesn't. I don't know anymore. I would guess that it doesn't tho. Thanks for bringing that up.
