If you've ever tried to make a house made of cards, you will appreciate this one. Bryan Berg broke the Guinness World Record for the World's Tallest House of Cards in 1992 at the age of seventeen, with a tower fourteen feet, six inches tall. His latest record-holding structure in the category is over twenty-five feet tall. In 2004, Guinness created a new record category for the World's Largest House of Cards to recognize a project Berg built for Walt Disney World--a replica of Cinderella's Castle. He continues to hold both records.
"The cards stand up–and stay up–for two reasons. First, there are so many cards in large constructions, the combined weight of all the cards actually adds to the stability of the structure. Second, the weight is supported by the strategic arrangement of cards, called grids. Cards, arranged in grid patterns, resemble waffles or ice cube trays. The cards actually prohibit each other from bending and also prohibit each other from falling over. If you can learn to build a grid structure, you can build just about anything." I bet he has a blast knocking down his structures as much as he likes building them..
