The whole frozen robot thing got me thinking…
When you freeze most things they contract (shrink up). I work in the satellite industry (i’m only a artist/animator though) and there are big lists of how much any given material expands when heated in the sun and contracts when frozen in the earths shadow.
Anyway, thinking back to my childhood, I used to freeze my Han Solo toy in ice (ala Empire strikes Back) and the ice would expand (I think) and crack the cup it was in. Same thing with icecubes.
Does the ice break the rules and expand when frozen, or does the plastic of the cup or the icetray just contract more than the ice does?
