Card by card history of how i failed to do this easy thing Building a house of cards (also known as a card tower) is a pastime involving the stacking of playing cards on top of each other in order to form a structure. The structures created using this method rely on nothing more than balance and friction in order to stay upright. No adhesives or other external connecting methods are used, and no damage or alterations are made to the cards themselves. The larger the structure, therefore, the more likely it is to fall, due entirely to the higher number of balanced cards that could fail and compromise the integrity of the card building. Bryan Berg claims, however, that the more cards you place on the tower the stronger it becomes. This is because the weight of the cards pushing down on the base (increasing friction) allows a few cards to stumble without the entire structure collapsing. House of cards is also an expression for a structure or argument built on a shaky foundation or one that will collapse totally if any one element is removed. World Records A prominent house of cards builder is Bryan Berg. Berg broke the former world record in 1992 for "The Tallest House of Cards" with a tower that stood 4.4 m tall. Another tower was built by Berg at the Department of Architecture at Iowa State University in 1998. It stood at approximately 25 ft (7.5 m) tall and utilized over 1500 decks of standard playing cards that weighed over 250 pounds (115 kg). It took two and a half weeks to build, with construction taking place in shifts that lasted anywhere from four to twelve hours each day. During construction, the tower was surrounded by scaffolding, which also formed the means of reaching the top of the tower to place additional cards. When he was asked whether it would be possible to build even taller (reaching for instance, about 100 ft or 30 m), he just responded with a simple: "You bet!" In 2004, Guinness added the "World's Largest House of Cards" as a new category in recognition of Berg's construction of a replica of Cinderella's Castle for Walt Disney World. [2] At the time of writing (August 2006), Berg was still the holder of both records.
