Heat a mixture to 100 degrees F without a thermometer?

[KeithTalent]

What the fuck, I made bread for years in restaurants just using my fingers to test temperature. It's not that hard, just don't have it scalding hot, but hotter than luke warm.

Freaking dang it, man hands. Why do you have to come up with a more sexy idea than me?

thats why they pay me the big bucks

Hot tubs are not supposed to exceed 104 degrees F. They're designed such that you can't raise them beyond that temperature. 104 is rather warm to submerge your body in, which will feel different than a shower.

Put two fingers in the water, if it is too hot for you to keep it in there for any extended time period, then it is too hot. It should feel very warm to hot, but not too hot.

Anyway, you can try cooking the milk (in a sealed vessel) in boiling water in a vacuum chamber. Adjust the vacuum level to roughly 27.5 inches Hg.

Maybe I will go see how much a thermometer is tomorrow and if it's cheap I will pick one up, otherwise I'll just check it by hand.

Another trick, put water in a cup, put the cup in whatever you're boiling, when the water in the cup starts to boil, you hit 100C.

Liquid expands when it gets hotter, you can also use this to make a crude thermometer if you are stuck. Made one as a kid using a mason jar and a straw for a school project. I put it in the freezer and when the water started to freeze I marked it as 0. I then left it in room temp for a while then marked it at whatever the thermostat was saying. I was then able to linearly mark the other temp points. Not sure how accurate this contraption was but it was a proof of concept.

It's probably easier to just buy a real properly calibrated thermometer. 😛

It's not a trick if he needs 100F.

Oh right, for whatever reason I automatically thought the temps equalized at that point like they do at -40. Brain fart.

Find a liquid that is known to boil at 37C then. 😛

Get a cooking thermometer...

I have a meat thermometer I got for $5. It's accurate +/-5C, I think.

Ya, about tap water. Weird. I never knew how low my temperature tolerance was until I decided to screw around with a thermometer (before the meat one I got) under the tap. Turns out the hot water out of my kitchen at full blast is only about 55 C. Thought it'd be at least 70 C.

Hey, great idea!
And its perfectly safe (citation needed).

Maybe your thermometer is off by more than you think 😛

 

[Red Squirrel]

Was curious so I tested my water

cold: 4C (actually warmer than usual, I've seen it at like 0C before)
hot: 55C

At around 45C it was no longer tolerable on my skin. I imagine in a hot tub or shower it would be lower than that, maybe 40C. I love a very hot shower though, so in the morning when I'm super tired my tolerance might actually be higher. I practically have the hot water jacked to the max, and I put the regulator inside my faucet to it's max setting.

Maybe. But I took another thermometer AND a $3000 infrared camera to triple-check.

Maybe your other thermometer and infrared camera is off, too.

4x independent verification is the only way to measure your water temperature :awe:

70 C would be dangerous. as in burning.

You thought the C to F conversion was hyperbolic? That's the only way there'd be 2 intersection points, which doesn't make any damned sense.

 

[Rakehellion]

I have a bread recipe that I'm making and I need to heat milk over a stove to "100-110" degrees F. Is there any way I can get it in this range without a thermometer? I don't have a liquid thermometer.

Maybe you should walk 5 blocks to a 7-11 and pick up a thermometer so you don't screw up the recipe.

 

[Mixolydian]

it will heat to 100 degrees regardless of whether or not you have a thermometer.

 

[SlitheryDee]

Yeah, and then it'll go right past that on it's way to 212 or so. The trick is knowing when to stop it.

 

[pete6032]

Was lucky enough to pick up a thermometer at the grocery store for $4.99. I'll let you know if 100 degrees is scalding hot.

I think I found the artist:

Nice to see he can still get work.
