Record-breaking Lego tower built in South Korea

If you have half a million pieces of Legos lying around the house you might want to take a stab at a world record. That's how many bricks it took to assemble the tallest ever Lego structure in Seoul, South Korea, which measures a whopping 105 feet from top to bottom. Built to celebrate Lego's 80th birthday, the colossus was stacked together in five days by 4,000 children. (We're happy to say there were no deaths reported during construction.) Danish Crown Prince Frederik, a royal in the country that invented Lego, was on hand to lay the final brick.
