And it makes your tummy feel better. Bismuth master race

[-] village604@adultswim.fan 17 points 5 months ago

But it can also make your poop black, so be prepared for that so you don't go running off to the hospital for intestinal bleeding.

[-] dejected_warp_core@lemmy.world 9 points 5 months ago

Combine this with beets for an extra good time.

It can also make your tongue turn black if you do the Pepto bismol chewy things

[-] village604@adultswim.fan 2 points 5 months ago

Yeah, my wife learned that one the hard way when she ate one before bed. Had quite the shock in the morning.

[-] HeyThisIsntTheYMCA@lemmy.world 1 points 5 months ago

and smell better too

Glad to see some bismuth love, but c'mon.

"Every single metal element" then calls out copper & gold separately.
No respect for chromium, which probably has more colorful compounds than any metal.
No cobalt either?
Manganese can be quite coppery; palladium and ytterbium can be gold-ish.

I know it's an oxide, but you allowed bismuth!

[-] Pringles@sopuli.xyz 11 points 5 months ago

What about pyrite? Or Iron Maiden?

[-] Ashiette@lemmy.world 9 points 5 months ago

Pyrite isn't a metal. It's an oxide.

[-] Pringles@sopuli.xyz 2 points 5 months ago

That's what it wants you to believe.

[-] toynbee@lemmy.world 2 points 5 months ago

In-A-Gadda-Da-Vida, baby.

[-] jaybone@lemmy.zip 2 points 5 months ago

Wrong Iron.

[-] toynbee@lemmy.world 1 points 5 months ago

I disagree.

[-] blockheadjt@sh.itjust.works 11 points 5 months ago

I wonder if there are some metals that appear grey to us but actually have a color, we just don't see it because it's outside our visible spectrum

Uranium is neon blue:

[-] RustySharp@programming.dev 28 points 5 months ago

... when charged particles move faster than the speed of light

So that got me curious, and found this

nothing travels faster than light in vacuum, but light can be slowed down and something can travel faster than this "slower" light

Somehow I've gone through decades of life without knowing this..

[-] Ephera@lemmy.ml 6 points 5 months ago

What also surprised me is that the speed difference depending on medium is actually quite substantial. For example, glass has a refractive index of about 1.5.

So, the speed of light in glass is c/1.5 ≈ 200.000 km/s, i.e. 66% of the speed of light in vacuum.

uranium itself isn't, anything will glow that colour if it undergoes nuclear fission underwater.

[-] KingGimpicus@sh.itjust.works 1 points 5 months ago* (last edited 5 months ago)

Actually uranium is a really bright yellow color. It's called "yellowcake" during processing..

[-] Dicska@lemmy.world 10 points 5 months ago

That is the very definition of colour. The part of the electromagnetic spectrum that we can see. The rest of the scale includes infrared, gamma or X-ray. If you want, you can call them invisible colours - or you can call green superhighultraviolet.

[-] scratchee@feddit.uk 9 points 5 months ago

In everyday context yes, but it’s pretty common to use “colour” to refer to frequency outside the visible range, and it’s interesting to consider what interesting “colours” we are missing out on because they’re outside our visible range.

Silver/grey implies even response across the spectrum, and is the normal expectation.

If we couldn’t see yellow (red/green) then gold would presumably look silver to us, so are there silver/grey metals that would have an interesting colour if only we could see it?

[-] blockheadjt@sh.itjust.works 4 points 5 months ago

If a bee sees a color we cannot, it would be pretty silly to insist it's not a color on the basis of us being unable to see it, wouldn't it?

[-] jaybone@lemmy.zip 4 points 5 months ago

Are there creatures that see radio? (Which I suppose is pretty general.) if so, they must hate us.

[-] 5in1k@lemmy.zip 3 points 5 months ago

Color is visible light in the human spectrum. We would say they see in the ultraviolet or infrared spectrum. Non human animals don’t use the literature so it’s designed with human perception in mind.
