If you're going to make a video about pyrotechnics, be careful, someone could get burned. In this case it was the director Michael Bay.The American Chemical Society makes fantastic videos that explain the appeal of Sriracha, and, in a separate video, whole-heartedly encourage peeing in the ocean. They're usually at least as funny and informative as the Bill Nye videos you'd watch when your science teacher was tired or hungover or gone.This latest one once again top notch, explaining the art of explosions in movies. I, myself, learned that dynamite is made of TNT and nitroglycerin, which I found fascinating because I had heard of all three things. I also learned a great new word: "brisance," which is the "shattering effect of a high explosive." Let's all try to work that into a conversation soon.The other thing that really jumps out at me is how willing the ACS is to slag off Michael Bay. "He's taught society that in the face of a half-baked story and a thin script, big budget explosions can help you save face at the box office," the narrator says.I mean, I don't really feel all that strongly about Michael Bay either way—I can't say I've followed his career all that closely but I really liked Bad Boys as a kid and feel that if you're seeing the movie Transformers on purpose, Bay probably delivers what you deserve. I just didn't know that the ACS that brisance* in them.*On second thought, maybe that doesn't work.
