"Originally known as “automatic binding bricks,” the snap-on blocks were invented in 1947 in Billund, Denmark, by toy-maker Ole Christiansen, who coined the word “Lego” from the Danish phrase leg godt, which means “play well.” They have been inspiring would-be engineers and architects ever since. The discovery centers, with their blinking, honking, cacophonous play zones, are designed for kids. Adults must be accompanying someone seventeen or under to enter—except on monthly adults-only nights, when grown-up “Lego geeks” are welcome."
