Have you ever tried to make a house of cards? Bloody frustrating and delicate work. I've tried a few times, but generally don't get above a miserable 2 levels. The guy in this story makes TOWERS of cards! He uses a technique called "grids"
What makes them stand up?I must give it a try.
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.
