Cheap thermometer calibration technique?

[Archimedes' Lever]

Go on, poke fun at me, what would actually happen?

If it is a resistor bolometer, one can burn it up by pointing it at the
sun.

Some have integrated FETs, and it would blow that... too.

Have I got really rubbish thermometers? I've tried measuring body
temperature both in my mouth and under my arm, and it's never more than
about 30C.

Probably. I just tried a couple of inexpensive IR thermometers, and
both read between 36 and 37 degrees C while looking into my mouth.
Sounds about right (though I'm not about to check it using a bare
thermocouple).

I noticed that my typical Fluke IR thermometer only works at room
temperature. I took it outside last winter, and after the unit starts
to cool, forget it.

Was it inaccurate only while cooling down, or did it remain inaccurate
once fully cooled to outside temperature? The sensor's own temperature
matters, and there should be a thermistor or something to measure the
sensor temperature and compensate for it, but this can be screwed up if
temperature is changing rapidly.

STICK IT UP YER ASS! :-] Hehehehe!

And if next time I forgot I'd done that, and stuck it in my mouth?

Have you ever heard the term, "wash"? And a healthy ass shouldn't have
anything harmful in it - it's inside your own body, right?

But some parts of the body aren't supposed to come into contact with other
parts.

....
Well, it is true that you can't touch your ear with your elbow; are you
talking about the "naughty bits"? That's just the body shame that got
programmed into you by strict religious parents.

Try feeding the exhaust pipe into the air intake in your car and see if
you can drive it a fair distance.

This makes no sense whatsoever.

Not as much backpressure as a spud.

That should have said "Try to feed the exhaust pipe into the passenger
compartment, and see if you can drive it a fair distance."

Hehehehehhee! Reminds me of Slaughterhouse Five...

 

[Rich Grise]

My parents aren't religious, luckily. Or I'd have been thrown out of home
for making fun probably.

Are you seriously suggesting that excrement is safe to eat?

Some animals _have to_ eat their own excrement - notably rabbits.

But I'm not suggesting you take your rectal temp. when your rectum is
full; and you'd wash it before putting it away anyway.

Cheers!

WHY?!?

I don't know about rabbits (maybe something to do with digesting
cellulose in grass, which is notoriously difficult to do).
Cows do something similar, but it's done internally (i.e. chewing
the cud).

Many animals have to eat their parents' excrement -- that's how
they get the right bacteria into their gut to breakdown the type
of food found in that locality. Elephants are probably the best
known example of this, and adults will also repeat this if they
are moved to a different location where the diet changes.
