and they glow blue when...

they're like... tiny semiconductors?

so back to perovskites

okay

because reasons

so why isn't the sky green

rayleigh scattering or something

so the sky is blue because...

oh right

it's just reflecting the sky

the ocean isn't blue

wait what

idk ask a fish

like why is the ocean blue

blue is the hardest color

but blue

so like... a tiny lightbulb?

light emitting diode

wait what's an led

i love it

this is the weirdest convo

so we're making tiny leds

got it

but for tiny crystals

kind of

so like... water?

no it's hydrogen bonds

is that like... duct tape?

okay but the quantum glue

wait it is
