Now of course, it’s not practical to simply stack Lego blocks until the bottom one is destroyed. For all we know (knew), you’d end up in orbit, where’d you float helplessly out into space. Instead, engineers used a hydraulic ram to crush a typical 2×2 Lego brick while a load cell measured the force being exerted. The end result? A 2×2 Lego brick can hold a staggering 950lbs (432kg), or 375,000 bricks.
Any more weight and the brick essentially melts, continuously deforming as more pressure is put on it. And while a tower of 375,000 bricks would theoretically stand 2.17 miles tall, Dr. Ian Johnston shoots the idea down, saying the structure would buckle long before completion. Let’s not forget the important question: can I live in a castle made of Legos?
