Spanish Human Tower Builders Set Record With A Tower 9-People High

Because dream it and, with enough people willing to risk broken bones you can achieve it, this is a video of Spain’s Castellers de Vilafranca setting a human pyramid record with a tower nine people high. Granted the very top floor of the tower is really only a half story because it’s just a child wearing a crash helmet, but still, I have to admire the fact they let a kid climb up there in the first place, then fall when the tower collapses. That would never fly here.

Keep going for the video, the kid goes up around 1:20, and comes back down quickly at 1:40.
