mmmm, I wonder how to make thermite...?
That's pretty dangerous. With a homemade potato cannon using hydraulic steel pipes, a sparkplug, a taser (connected to the spark plug to get it to ignite) and a tank of 100% copressed oxygen I put a potato spud thru a shipping container :-) That's when I realised I was mental and people were going to get hurt so I emptied the oxygen tank (slowly in an empty park I might add).
