I mean, you can heat any old rock & make it look like that ... what I'm saying is that every rock, when heated to 500+°C, will gain delicious orange flavour, but scientists don't want you to know that!!

I wanna taste that blue Cherenkov tang

[–] SippyCup@feddit.nl 59 points 4 days ago (3 children)

Evidently plutonium just tastes metallic. And radium is flavorless.

What I'm saying is people have tasted these things.

[–] baldingpudenda@lemmy.world 27 points 4 days ago (3 children)

I think it was when we got to toxic metals and radioactive elements that chemists where forced to stop tasting their discoveries.

I hope it went: Safety person: Hey! Stop tasting any elements or new molecules. It's been getting people severely sick or killed!

Chemist: "Ugh, fine, but ima bitch about it the whole time"

[–] SippyCup@feddit.nl 19 points 4 days ago (1 children)

I believe the guy who tasted plutonium did so accidentally when the powder got in his mouth. The metallic taste probably has something to do with how radioactive it is.

[–] CommissarVulpin@lemmy.world 12 points 4 days ago (3 children)

Or the fact that it’s, y’know, a metal

I was about to say that in the 40s and 50s someone ~~probably~~ taste it.

[–] Anomalocaris@lemm.ee 7 points 3 days ago

Given that lead acetate is sweet, would plutonium acetate do the same?

anyone wants to help me set up a charity where we give "last meals" to terminal patients using toxic ingredients just for them to describe how they taste?

[–] boydster@sh.itjust.works 21 points 4 days ago

The best way to tell precisely how spicy your rock is, is to taste it. That's just basic science, if you ask me.

[–] Evil_Shrubbery@lemm.ee 17 points 4 days ago

Zomg, where are all the warning labels???

Yeah. That looks like something Codyslab will do...

Wtf, no, you should not lick boron, fucking ever. Go lick a piece of lead, it's better for your health

[–] phoenixz@lemmy.ca 1 points 2 days ago

In order to lick something at the very least it needs to be liquid, or better yet, solid.

Trying to kick hydrogen, with this in mind, will be the last lick you ever do in your life

Fun fact: a gram of plutonium contains about 20 billion calories. Yum.

And it goes straight to my hips. By which I mean the bone marrow in my pelvis.

Not dietal calories.

The calorie numbers we assign to food, measure how much energy our body extracts from them when eaten.

In this context, plutonium is closer to 0

If we instead want to measure the actual total physical energy content of materia, we would turn to E=mc^2, telling us that a gram of anything has about 20 million kcal, no matter if its plutonium or diet coke. which is a slightly less useful value on food labels :D

[–] socsa@piefed.social 3 points 2 days ago

This is actually an issue with food calories as well. Wood shavings give a high reading in a bomb calorimeter but you can't process them into energy. Same with lots of fiber. And ethanol, in some cases.

[–] atomicorange@lemmy.world 22 points 4 days ago* (last edited 4 days ago) (3 children)

Technically it measures how much you can heat up a known volume of water if you burn the food. We have no way of measuring how much of that energy released by combustion actually gets absorbed and translated to ATP in the body, but it’s the best estimation we have of the relative energy content of foods.

There’s some carbohydrates, proteins, and fats that our bodies don’t seem to convert to energy (or only partially convert) but still technically contain “calories” because they’re combustible. Sugar alcohols, fiber, etc.

Plutonium doesn’t combust, but it would heat up water in a calorimeter. Really the test method’s applicability kind of falls apart when you start testing undigestible materials.

This is a commonly quoted fun fact that is not really true. There are 2 different definitions of calorie. One means the absolute amount of energy in an object, the other means the bioavailable amount of energy that a human can extract from it using their digestive system.

So every physical object that exists has some amount of potential energy contained within it which we can express in calories, but that doesn't mean it has any bioavailable calories. For example glass has some significant amount of energy contained within it, but it has 0 bioavailable calories.

This "fun fact" mixes up the two definitions, making the statement meaningless.

(Nothing against you OP, this is a commonly repeated falsehood)

[–] Evil_Shrubbery@lemm.ee 24 points 4 days ago* (last edited 4 days ago) (2 children)

this is a commonly repeated ~~falsehood~~ obvious joke

And, if I have to explain the joke: it's just E=mc² (the Einstein thing ... well, the Einstein's thing's approximation), the energy (E) is the same for all mass (m) since the c is a constant.
You get the same 21 billon kcal from 1g of apples as from 1g of plutonium.
And since it's usually well known humans do not devour mass into pure energy that might trigger ppls sense of humour.
(Additionally the idea of eating metal to seek nutrition might be funny, but we do need some metals \m/.)

Also "potential energy" phrasing is weird in that context.

There are 2 different definitions of calorie.
This "fun fact" mixes up the two definitions

It's not even two definitions, the kcal is absolutely the same, it's just used to measure two different things (mass energy vs the sum of what an average human can extract via chemical processes). I see you def understand that, but it's not a different definition of a calorie (in the same way as length vs width of an object isn't a different definition of a metre).

If you eat just one bite you'll never have to eat again for the rest of your life!

Equivalent-level of fun fact: 1 gram of hay contains that much calories too!

We need a cosmological law dictating harmful to humans = boring-looking. I mean, it isn't just plutonium, look at uranium yellowcake! It's lemon flavouring!

Isn't it just that color because it's hot? Like, if you cooled those off to room temperature, wouldn't they be metallic gray?

This whole image is metal as fuck \m/

[–] expatriado@lemmy.world 20 points 4 days ago (1 children)

if you can wait a few million years, after few decay steps it turns into lead, which is known to be sweet

[–] VerilyFemme@lemmy.blahaj.zone 18 points 4 days ago (2 children)

Yes, it does look delicious.

But I can't help but think about this being the consequences of dying everything we eat unholy colors. Maybe radioactive material wouldn't be so tasty looking if we didn't give kids candy that looks like radioactive material.

It is for sure delicious, but those who tested, never said it
