If really gold, the weight would snap the plywood sheets. I say its fake.
I disagree with you on that one. The plywood sheets aren't carrying the full load above them. You can't see this easily because the labels are in the way, but each pallet has another vertical support running down the middle of it. So it looks as if there are only about 12 inches between each support -- which means these pallets are not the typical industrial pallets you see in a warehouse.
Actually, with the load being so evenly distributed, the wood should hold up. If you notice the horizontal boards do show some deflection. I will run the numbers later to see if the mechanics equations bear the same results, but I'm pretty sure they will. I load 300 hp motors onto wood palets all the time and that is a force of 400 lbs only over 16 in^2.
