One of the few places (fortunately) on the planet you can find polystyrene cups these days is #oceanography store-rooms. We send them down with our CTD* instrument packages to the depths where they get nicely pressurized and come back as very pretty thimbles. Its a great activity to combine with school talks but school is out of session so we have to step in as kids with colouring pens - not hard 😃 - *and timely as its less than a week until #CTDAppreciationDay
