I may be a grown up, but I still can't stop talking about Legos. As part of the World Children's Festival, hordes of kids recently showed up at a giant Washington, D.C. playground with thousands of mini building blocks. They showed off their creative skills by creating skyscrapers, bridges, railways, and even Las Vegas hotels. The real life LegoLands, which are located in the US, Denmark, UK and Germany, use about 1.6 million tiny plastic bricks. Other cool Lego trivia I've picked up along the way? Only one percent of the plastic waste in Lego factories goes unrecycled and Lego Group produces over 306 million miniature tires each year - more than any other tire manufacturer in the world. That's a whole lot of Legos.
