Intrepid Sea, Air & Space Museum LEGO demonstration

Revisit a childhood pastime at the Intrepid Sea, Air and Space Museum where British artist Ed Diment will spend most of the weekend building a 22-foot-long, 550-pound replica of the aircraft carrier out of LEGOs (he's built one before in his native U.K.). Diment will also give tips on constructing smaller military vehicles—he may just inspire you to break out an old set and get creative.
