Ever since I came across this video https://youtu.be/gy5g33S0Gzo?t=4 of a robot taking 1,5 hours to fold five towels, with mixed results, I think about how much of our brain might be devoted to handling fabric every time I have a towel in my hands. Probably the same with handling fluids, like predicting how milk is going to behave in an opaque carton.
