Status: Just got a delivery from Amazon Fresh (wanted to try their delivery service for groceries because they have some stuff which is sometimes a bit of a hassle to get).
Turns out that if you order stuff that's supposed to be frozen they use dry ice to keep the food frozen during delivery.
Three guesses whose appartment now partially looks like a mad scientist's laboratory? And the first two don't count.
I'll have to get some food colouring or something to see if I can get coloured fog streaming out of the containers...
