I'm sure many of us are familiar, if not rather fond of Lego, the colourful little building blocks you played with as a child (or maybe still play with today). As world records go, the tallest Lego tower doesn't seem that out there compared to other attempts, with it simply being a question of who can build the highest. It also happens to be Lego's 50th anniversary this year so the tower, built at Legoland in Windsor, UK is a celebration of that milestone as well as being the tallest tower yet built. It gobbled up a staggering 500,00 bricks and reaches the giddy height of 100ft (over 30m). Children who visited Legoland over the weekend helped to complete the tower by making 20cm sections, which were added with the help of a crane. The record should be confirmed by Guiness World Records somtime soon.
