Chemistry isn't just a boring subject you slept through in high school—it's also nature's pyrotechnician! Copper gives us those stunning blues, sodium flashes bright yellow (just like those warning labels on your lab coat), and barium makes green that would make environmentalists proud. But then there's uranium... because apparently regular fireworks weren't dramatic enough. Someone decided "let's just skip the pretty colors and go straight to apocalyptic mushroom cloud." That's not a firework, that's just showing off at a nuclear level. Next Fourth of July, remember you're basically watching excited electrons return to ground state—except for uranium, which is just ground... into dust.
