Oh the humanity!
The other thing that folks forget is simple displacement. Take their large pot. Fill it 80% with cold oil. Heat the oil to boiling. It expands a bit and now the pot is 90% full. But how are you going to reduce the amount of oil now? It’s too hot to ladle it out, and what other big pot do you have to put it in, and you don’t want to spill oil on your shiny new wooden deck.
So you leave it. And prepare to add the turkey, not considering that it’ll displace a volume equal to about 50% of the oil. Which has to go somewhere.
As you start to lower the turkey you get some spattering. Ounce for ounce it’s no worse than chix wings on a stove-top deep fryer. But there are more ounces and some bigger splatters hit you. Now you panic & drop the bird. Which falls into the pot, triggering a massive overflow, aided and abetted by a lot of ice-flashing-to-steam splattering. Which overflow spreads to the burner and the deck, igniting the whole mess with an impressive FWOOF!
Which with any luck burns the house down.
Such fun. Morons.

I like the way you think. We need you over in this thread.
I am both surprised and disappointed.
Next, though, I would like to see a similarly sized solid block of ice. Then we compare ice cubes to small bits of dry ice. Is is a surface area issue?
Of course, that was just wild speculation on my part. It was a joke. If you went to the local industrial gas place and asked for some solid H2 they’d just laugh nervously and say something like “Sorry, we’re out of that now, but it’s on back order. If you’d like to leave us your name, address, and phone number we’ll let you know when we get some in.” And then some people will visit you who will ask you a LOT of questions.
Oh, and that’s just a wild speculation on my part too.
But surely “turkey” would have fitted into this sentence perfectly well?

Hot to cold oil isn’t going to go from 80% - 90% full from heat expansion. The increase in volume is pretty negligible. All the panic and burnination is due to idiots either forgetting about displacement altogether, or guestimating the amount of displacement instead of placing the turkey in the fry pot, filling it with enough water to cover, removing the turkey, and then marking the lower water level as a reference point for adding the oil, which is the proper method.
