Let's keep on exploring the Fair!
The DuPont pavilion looks like a miniature baseball stadium here. Each of the globe lights that surround the building are surrounded by "atoms", making them into stylized molecules. This pavilion sounds like one that I would want to visit... among its wonders: You'll see a performer place on his hand a piece of metal heated to 1800 degrees, protected by a sheet of insulating material only one-eighth of an inch thick. You will witness curious and startling reactions, such as the mixing together of two clear liquids which suddenly and on signal turn black. You will see a liquid change colors many times as it is poured from one container to another, and you will marvel at the strange and beautiful effect of chemiluminesence. Chemiluminesence, yeah!!
And, just because I love him, here is Mr. T. rex from Sinclair Oil's "Dinoland". I recently watched some video that showed many dinosaurs from this exhibit, and lots of them had movement. It didn't show the T. rex, but I think it's safe to say that his arms and jaw moved, and it's possible that his head moved as well.
