This hardware hacker was experimenting with liquid cooling for an old motherboard, immersing it in oil in a tin pan. Once that worked, he decided to heat the oil up and make french-fries in it, while playing Quake on the PC that was being slowly deep-fried along with the chips. It worked for a while, then the machine had to be rebooted (and it continued to work after that!)
Eventually, though, the strain of 120 degrees C ambient temperature and the load of Quake 3 caused the computer to overheat and crash. I rebooted it, and it loaded back into windows. Although Quake 3 still crashed when trying to play. At that point, the chips were ready. I turned off the heat and enjoyed my snack while I waited for the oil to cool so I could use the computer again.
