Interesting FAQ from the card stacking world's record holder.
Do you EVER tape, glue, fold, bend, or manipulate the cards?
NO. None of my structures involve trickery. They are the "real deal."
What makes them stand up?
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.
