I'm glad that the Chinese invented fireworks. I love to see the pretty colors in the sky! (And I love to see how modern pyrotechnicians have developed ways to make them prettier - new colors, new detonation techniques that form butterflies,heart shapes, and ringed 'planets" in the air. I left my time machine in my other pants, but if I'd known then what I know now, I'd have majored in chemistry or chemical engineering instead of physics, and I'd probably have become a pyrotechnician. (One of the guidance counselors who helped my son a lot when he was a troublesome child was a retired pyrotechnician. I never got a chance to sit down and chat with him, dammit.)Or maybe I'd have gone into food chemistry.
