I especially like this Google Science Fair 2012 video, because it shows how much makeshift and creative improvisation takes place in laboratory work—quite to the contrary of the usual renditions of hight-tech labs in movies. And I of course do like it, because Lego is used. Another instance of Lego serving science is a recent publicity stunt: The personnel of the German research-station ↑Neumayer III in antarctica are ↑recreating their station out of 7000 Lego pieces [in German]. Seemingly as a kind of group therapy to overcome the boredom during the antarctic winter :-)
