I've been reading this information about fridges, which sounds really boring but I actually find it really quite cool, it reminds me of this article in new scientist about phase changing materials being used to keep buildings cool, with them it was melting and freezing instead of evaporating and condensing, either of these is pretty weird and shocking when it happens in anything that does it to a different temperature to water, the mental images it conjures are alien, like liquid nitrogen, weird.
