Did you know that the catalytic converter on 4-cylinder Toyotas can glow red when at maximum operating temperature? (glowing red steel means the temperature is approximately 830°C, which is upper 1000s in Fahrenheit) Did you know that it can continue to glow red for up to a minute after the car is off? Did you know that the oil filter on that engine is less than three inches away from the catalytic converter?
Did you know that touching glowing red steel for less than a quarter of a second can melt skin? Neither did I until last Friday. The penny is there for scale. The entire pink area has healed since last week, and every morning I wake up to find that the scab has rubbed off and my hand is covered in dried blood. For the first week, the scab was quite crusty and bloody, so what you're seeing is about 5 times better than it was originally. It still hurts like hell when I don't hold it up and gravity pulls blood toward the cut, and I'm looking at another two weeks until it's past the open cut stage.
Edit: I work at a quick oil change shop, and I've also fallen in one of the pits. They're not kidding when they post signs saying "CAUTION - OPEN PITS - DO NOT ENTER"
Double edit: misspelled "edit" the first time
