Holy stuff, I'm having so much fun with this. All the new pressure + temperature monitors are really useful. I just made a uranium powered stove, and even after releasing all pressure, that stuff stayed at ~ 10,000 degrees C.
So I poured liquid nitrogen and ice and snow all over it, so the heat left the uranium (only about 1,000 degrees of it), and it was all transferred to the water vapor which burned right through my metal pan that I put on the stove.
Edit: Holy stuff, I was making a gas-powered air gun, but i forgot that noble gases turn into plasma when electrified, so instead I made a freckin plasma torch :D
Moar edits: So much loving fun :D I just made a noble gas light bulb, and when it shatters, it spits out plasma and lava :D
