House of Cards

This will be the most amazing house of cards you will build in your life!

Flat surface (preferably carpet)
deck of cards (15 cards per story)
steady hand

Lean two cards together vertically (forming a triangle) with the bottom edges one inch apart and the top edges flush.

On one face side of the triangle, create a bridge with two other cards: one horizontal, one vertical.

Repeat on the opposite side.

Parallel and directly to the side about two inches away, repeat steps 1 through 3.

Bridge gap between two structures with three cards running perpendicular to existing structure.

Repeat steps 1 through 5 on top of existing structure at a 90 degree angle to existing structure. See how many stories you can build!
