I think that is just an expansion of what he already did. He lifted the one block up to lay horizontal at 3 feet high. You expand that out to 12 feet, then stand two blocks on the sides. Then you just lower your top block down on top. It would take time but after seeing this video I can definitely see how it might be done. And keep in mind that this man is doing it all by himself. You get a hundred people together all doing the same thing and helping each other and it could be done.foshizzle said:I want to see him put a block on top of a couple of those... then I'll consider him a genius. Elegant solution for sure.
