Would a styrofoam cup actually stay in reasonably good shape for 400 years after being buried?
Mostly a curiosity thing. I sometimes use styrofoam peanuts in planters for drainage purposes, and after a single growing season, they’ve already started to show signs of degrading. Not that microplastics are a good thing, but it also makes me wonder if they would actually stick around in good condition for 400 years.

If it’s actually make out of polystyrene, I’ve read that is supposed to take 500 years like a lot of other plastics.
Many packing peanuts are biodegradable these days though, so it might not be actual styrofoam (polystyrene + air).
I think the new ones are made from potato starch
Those packing peanuts are made from corn and are basically edible.
Or if you wet them, they get sticky and you can stick them together to make stuff.
