My friend calls pineapples 'Dragon Eggs' and tossed one into a bonfire. Pulled it out later to have the most delicious roasted sweet mythical egg ever

[–] notabot@piefed.social 91 points 2 weeks ago (2 children)

Sounds tasty. I can vouch for lemons undergoing a similar transformation. Wrap them in foil, seal it really well, and chuck them near a fire or bbq. They come out soft, sweet, and delicious.

I would like to subscribe to lemon facts.

Lemon Facts

Thank you for your interest in subscribing to Lemon facts. Here are some sample facts to get you started:

  • The lemon tree is evergreen of the family Rutaceae.
  • They are a hybrid of the bitter orange and citron.
  • The most common variety seen in supermarkets is 'Eureka', which fruits throughout the year.
  • Lemon juice is a natural cleaning agent. Mix with water and, optionally, vinegar for a handy glass cleaner.
  • Two lemons are enough to provide your recommended daily intake of vitamin c.

You can subscribe to more Lemon Facts for just 10.99 per day! Please reply with your creditccard details to subscribe, or 'disagree' if you do not wish to subscribe at this time. We may retain your details to offer you the opportunity to subscribe to other lists in future.

Before Maillard invented his reaction in 1912, you would have just gotten a burnt lemon

[–] Viking_Hippie@lemmy.dbzer0.com 10 points 2 weeks ago

That was nice of him! Thanks, Maillard!

Like, in the middle of the fire? For how long? Wanna try it in the future

[–] heyWhatsay@slrpnk.net 15 points 2 weeks ago (1 children)

Tossed it in when the fire was at peak flame, and then waited for the wood to burn, the pineapple looked like a big piece of black coal

[–] rotateabull@lemmy.ca 10 points 2 weeks ago (2 children)

I need to try this. A full pineapple into the flames naked?

[–] heyWhatsay@slrpnk.net 23 points 2 weeks ago

Pineapple can be naked, if anyone else is naked, I suggest not jumping into the flames

[–] Hadriscus@jlai.lu 6 points 2 weeks ago

It works for breadfruit as well, my favourite way to cook it. You'd believe it has turned to charcoal, but no, the inside is like sweet bread fresh out the oven. I like to cut it in half and scoop it out with a spoon

[–] iAmTheTot@sh.itjust.works 17 points 2 weeks ago (3 children)

Roasted pineapple is delicious. Coat it on some brown sugar, roast it, then carve off the toasted bits. Repeat.

[–] JetpackJackson@feddit.org 3 points 2 weeks ago

I need to try that

Mother of pineapples

[–] Bubs@lemmy.zip 85 points 2 weeks ago (5 children)

1000°c seems accurate:

Fun little science fact: Heated objects glow the same colors no matter what they are made of. It's called Black Body Radiation. The color chart shows what temperatures correspond with various "colors" of glow.

[–] Natanael@infosec.pub 27 points 2 weeks ago

Heated objects glow the same colors no matter what they are made of

True only if light emissions aren't dominated by chemical effects or filtered by structural effects. Plenty of materials burn at different colors. Although if you wait out the chemical reactions and keep it heated, it does eventually end up with just blackbody radiation too 🤷

[–] icelimit@lemmy.ml 10 points 2 weeks ago

But corrected by emissivity factor. Emissivity factor is also not constant, and changes as both a function of material and temperature. Probably associated with band gap fluctuating wrt. Temperature

[–] Gladaed@feddit.org 6 points 2 weeks ago

Unless it is a gray body. For somewhat accurate measurements you must do math.

[–] Agent641@lemmy.world 5 points 2 weeks ago (3 children)

Aluminium doesn't glow, even when molten though?

[–] i_love_FFT@jlai.lu 14 points 2 weeks ago

That simply means it must melt below 600°C.

A quick wiki check says it melts at 660. I guess if you're in a really dark room, you could see the glow.

[–] Gladaed@feddit.org 4 points 2 weeks ago (1 children)

Real bodies are gray, not black.

[–] BreadOven@lemmy.world 5 points 2 weeks ago

Which makes iron a suitable substitute for tungsten at 3000 C

[–] BurgerBaron@piefed.social 44 points 2 weeks ago (4 children)

I've been watching Tech Ingredients search for the best shield material to test their Drone destroying extreme high power laser setup indoors for obvious reasons.

It turned out to be fruits/veggies. Nothing else came close. So he went with panels filled with thickened water.

[–] dejected_warp_core@lemmy.world 24 points 2 weeks ago

That makes sense. The specific heat of water is a real bastard to overcome.

[–] IAmNorRealTakeYourMeds@lemmy.world 14 points 2 weeks ago (2 children)

I'm personally skeptical of laser based weapons, given that they have one wavelength. once one is developed and deployed, it will be trivial to paint drones with a reflective paint specific for that wavelength.

The results is a nation investing 100s of millions on a weapon, that once deployed will be countered by 1000s $ of spray paint.

imagine if you could get a t-shirt that could deflect a any bullet. that's what still happen with laser based weapons.

[–] wolframhydroxide@sh.itjust.works 19 points 2 weeks ago (3 children)

I think that wouldn't necessarily work once you get to the right wavelengths for it to start interacting with the organic bases of the paints. There's only so much you can do when someone shoots an infrared laser at the resonant frequency of a C=C double bond.

[–] burntbacon@discuss.tchncs.de 7 points 2 weeks ago (4 children)

Wasn't that 1500 whatever-the-unit-was? Below 1000 whatever-the-unit-was was the fingerprint bands, 3400ish whatever-the-unit-was was the O-H bonds, 3100ish whatever-the-unit-was was N-H bonds, 2900ish whatever-the-unit-was was the triple-to-C-H bonds, etc.

Ugh. The lab portion for that was so tedious. We would have to sketch the expected resonance patterns by hand for a bunch of different molecules. I loved the simplicity of the hydrogen bond nuclear resonance imaging so much more.

I never knew a disintegration ray was possible.

chemist was my weak point at uni. and I'm too tired to look that up, what's the frequency. I want to check if there are materials that can reflect it.

the coating doesn't have to be organic, a thin metallic coating might reflect the laser.

I'm not giving an expert opinions. but I'm personally betting that any laser weapon will be useless within weeks or days.

Sir Pinappleus the Hawaiian: You absolute fool.

[–] jaschen306@sh.itjust.works 31 points 2 weeks ago (1 children)

Related, but off topic.

If you ever visit Taiwan, be sure to eat the local pineapples. We have one of the sweetest pineapple and we eat the core of the pineapple. The core is actually crunchy, like the constancy of a crispy pear.

[–] crazycraw@crazypeople.online 19 points 2 weeks ago

so does this make my balls permanently sweet or what

[–] stupidcasey@lemmy.world 16 points 2 weeks ago (1 children)

The pineapple will be just fine the flesh touching the steam on the other side spread all over your body by the pineapple keeping it pressed against your skin on the other hand is going to have a nice chard bbq taste.

[–] pivot_root@lemmy.world 14 points 2 weeks ago

If the steam doesn't get you, the enzymes breaking down your proteins would surely give you horrible skin irritation.

Why was the pineapple discarded? They could have eaten it 😭

[–] stray@pawb.social 7 points 2 weeks ago

Don't worry. It's a black deck, so the graveyard is exactly where the pineapple wants to be.

and what happened to the card

[–] MonkeMischief@lemmy.today 3 points 2 weeks ago

It got dissed.

What it did to deserve that, we might never know. . .

Does it work when the skin is properly dried though? Armor would dry out over time.

[–] Test_Tickles@lemmy.world 9 points 2 weeks ago

Ya, it's all a big lie brought to you by billionaire dragons. They're just trying to get you to wrap yourself in a tasty garnish so that they get a nice citrus flavor once they are done roasting you.

[–] HowAbt2day 5 points 2 weeks ago

You’ll have to keep moist and wet. Oh so wet.

Iron? I suspect otherwise... My dear RHNB, I miss your red hot nickel ball.
