No, it’s not spaghetti waiting to be served in the Medical School cafeteria — it’s intestinal worms (Ascaris sp.).
Which demonstrates that some potential museum artefacts are just so much more evocative than others. (Maybe something for Damien Hirst to consider?)
I wonder if the worms can be preserved in alcohol fumes in a canteen-looking food container like that (with a glass lid on top, perhaps) to enhance the effect? Or does one have to soak them in liquid alcohol in a jar?
