Who told you to touch the thing?

I was taught turn it on when I turn on the lights, do mg light check and just touch it on the way back into the cockpit to verify it’s warm. One day the person before me had left it on and it didn’t occur to me that it was heating up the whole time the master was on and when I touched it it was hot af. Until then I never known how hot they got, had always figured lukewarm at best.

C-152 not much above ambient. C-310 3rd degree Burns (so I'm told)

They would have been helpful to suggest tapping it with the back of your hand…

“Don’t touch that.”
 
Try testing an ice detector (not the steampunk Hawker version) by touching the the little round tip of the probe, at first it will be ambient and then it will heat up so fast that if you don't back off you'll have a blister.
 
Actually the Hawker thing works pretty well, when I first started spending any time around those god forsaken weirdo designed airplanes I couldn't figure out what that probe might be. I asked someone and was told "It's an ice detector.". No one bothered to explain how it worked and I continued to look at it (and the rest of the airplane) like a suspicious feral cat.
Those ice detetectors are over engineered simplicity, just like the rest of the airplane.
