why the 4th of July is literally TOXIC

Happy 4th of July! Did you know that making a blue firework is so chemically fragile that it requires a precise 1000°C window, or the molecule disintegrates entirely? 🧊 Welcome to The Berg™ — we go way too deep on the things you never think about. ⏱️ CHAPTERS 00:00 Intro 00:00 The Surface 01:04 The Star Ingredient 02:08 Electron Dance 03:16 The Impossible Blue 04:18 Exploding Bamboo 05:24 Accidental Explosions 06:30 July 5Th Haze 07:36 Toxic Rain 08:45 The 170 Decibel Boom 09:52 The Drone Revolution 11:01 Resurface While we're all watching the sky today, there’s a lot more going on than just bright lights. From the ancient Chinese accident that invented gunpowder to the literal quantum physics happening inside every shell, we’re diving into the fireworks iceberg. We’re also talking about the toxic 'hangover' they leave behind and why drones might be the future of the 4th.
