We now know how many Lego bricks it takes to crush the bottom piece

12/4/2012

Hey, Lego nuts, sorry to spoil your fun, but scientists have solved the problem of how many Legos you can stack before the bottom one breaks. Still want to figure it out yourself? Stop reading now. But for the lazy-minded among us, the answer is 375,000 colorful 2-inch-by-2-inch bricks that would climb 2.17 miles into the sky. Unlike Redditors who've been trying to figure out this puzzle for a year with mind-boggling equations, arguing over buckling force and cross-sectional inertia, Open University brainiacs donned safety goggles and stuck a lonely Lego into a hydraulic testing machine until it collapsed. Thanks! That frees us up to ponder other pressing issues, like names for the royal baby. [Source]
