This shows you how to easily construct a 3D domino pyramid. First, line up your dominoes on their sides in a zigzagged diamond-shaped pattern. Then, stack dominoes on the left side facing vertically-going from one to another-on all the dominoes except the three in the top left side of the pyramid. Continue to build this way, moving up and alternating in placement in the middle of the diamond. Finally you'll work your way up to one top piece. Then you add a row of dominoes around the outside to your structure, and repeat your first steps.
