An interesting idea.
My fridge won't do that low.
Maybe a box full of dry ice?

Or a really big CO2 cartridge. An upside down can of air like used for
dusting out computers held upside down will squirt liquid CO2 at around -100
F. If you try this wear a very thick and well padded glove.

I've heard this old saw so often even I was beginning to believe it.
While it is based on fact, it's not seriously practical.

When released (in)correctly, it is true that a CO2 extinguisher will
make a pile of dry ice. But it's a very small pile compared to the
amount of CO2 gas released. It would have to be a Very Very Big (TM)
can in order to chill a that big of a slug of steel to below 0.

Simple thermodynamics, dudes.
