I’ve been tinkering with an alloy that shifts color with temperature, and I think it could give a punchline a whole new punch—wanna see how it reacts?

Here’s the thing: it’s a tiny disc about an inch across, made of a 58% copper, 30% zinc, and 12% nickel base, with a thin layer of palladium sputtered on the surface. When I heat it from room temperature to about 70 °C, the palladium layer goes from a dull silvery gray to a bright cobalt blue, then fades back as it cools. I can run a simple experiment—just put a 50 W lamp on a metal stand, switch it on, and watch the color shift in real time. Give me a few seconds, and you’ll see the light show.

Alright, set it up on a heat‑resistant stand, keep the lamp 15 cm away, and note that the color shifts most quickly between 55 °C and 65 °C—if you want a sharper punchline, I’ll adjust the palladium thickness. Just keep an eye on the temperature; the disc will freeze back into gray as it cools. Ready when you are.

Place the disc on the stand, set the lamp 15 cm away, and turn it on—watch it shift from dull gray to cobalt blue as it heats, then fade back as it cools. Safety first, but the show starts now.
