Eventully the Great Tower did fall, scattering Jenga blocks all over the kitchen floor. We were still finding them the next day! I think the final count was 28 layers, which is one of the highest I've seen in a while. Though at one point at Coffeehouse Matt, Pete, Cory and I had a pretty tall one, but we never counted the layers.
After Chris and Kyle were finished, Michael and Hendrik had some fun with the blocks. Here Hendrik is admiring his tower minutes before it would fall. I think the 2 of them spent 20 minutes building towers, and watching them fall, building towers and watching them fall. Amazing how much entertainment 54 little pieces of wood can provide!
