this video was so much fun to watch. thank you for posting it. I initially searched the term beryllium because I've recently noticed its use in a hobby of mine: the audio world. a company started using beryllium to make small dynamic drivers to go inside earphones. after watching this video, I understand why due to its rigidness and how fast sound travels through or across it.
I’m pretty sure the golden colored beryl is called Heliodor. From Wikipedia : Heliodor is the beryl variety that receives its yellow color from Fe3+ ions. The name "heliodor" originated as a trade name for golden beryl from Rössing, Namibia but now encompasses any gem-quality, golden-yellow beryl. Heliodor, Brazil.
How it is possible , to be both lighter and denser and harder without reducing its volume at same time ?? I mean if denser means its atoms are closer With others so it should take less volume then other elements like iron ????
... Beryllium ist a moderator - and in it also hidden Numbers 137 of mathematics in Barium Atom Mass 137 and Cäsium 137 - its fine dust number - so by big bang the Explosion and Expansion becomes slowlier and slowlier - but never Stop - it is just the critical expansion by using Beryllium as Reflektor.
SF200 beryllium contains about 2% BeO impurity and is stronger than steel. It has extreme hardness. Unless ultra pure (.999) it cannot be sawed , milled or drilled. Grinding beryllium would be very hazardous causing dust which could be accidentally inhaled.
**Because it's only toxic in fine, powdered form if you breath it into your lungs over a period of time. Holding a smooth, solid chunk of beryllium metal is no more poisonous than wearing emerald or aquamarine jewelry.**
I’m confused on the density. Why is he remarking on how light it is? If water has one gram per cubic centimeter of mass and beryllium has 1.85 gm/cm3, isn’t that more dense? Wouldn’t that make the beryllium heavier if you compare it to the same volume of water?
It's not "Columbia"... It's Colombia with an "o". One of you slides had that mistake. Very interesting. Would like to know what atomically properties makes Be so smooth? Or maybe that is too complex for the layman. Anyways, wonderful!
You're confusing pure beryllium metal with its highly toxic powdered forms if they are absorbed (pure Be or oxides etc.). On its own, pure beryllium metal is quite safe to handle, though yes, I'd prefer to stay away from it all together. Absorbed beryllium (in powder forms) causes subtle, long-term BIG problems to humans. It's such a tiny atom that it just 'gets in' and causes dangerous chronic inflammatory reactions. That cube of pure Be must be worth at least a few thousand dollars. It's hard to machine and mostly used these days for X-ray windows as it lets them through.
lol hidden double meaning of the beryllium sphere from an *airplane* being "one of the smoothest things" cause theyre also hiding anti gravity properties of gyroscopes
It is not known to cause cancer. Workers exposed to Be fumes or dust can and sometimes do suffer from some degree of chronic lung inflammation. Beryliosis that has progressed to granulomatous pneumonitis can be treated with glucorticoids and immunosuppressive drugs to lesson symptoms. Only a small percentage of beryllium workers are affected by beryliosis. Every time you handle most metals a few atoms rub off onto your skin. It is hazardous to handle beryllium if you have a cut to your skin. Beryllium has a sweet taste and oral ingestion has not caused any ill effects.
Best exposition of Beryllium ever!

Ha I am watching because the tweeters in my Focal studio monitors are beryllium. There awesome :)
Marvelous tour - thank you.
Thanks, got precise knowledge on beryllium

...why is he and the audience handling the metal with bare hands? Also, that's a valuable piece of beryllium!

*I did not know that*
You did not mention that beryllium is used for making diaphragms for speakers.
Cool!

I found a small chunk of beryllium and it has given me strange powers....
Won't you get berylliosis from touching beryllium?
No, the pure metal is reasonably safe. Just don't cut it and get any dust from it.
Where do you find it?
Jim Jardine eBay ebid or Amazon,mine was ebid and my red beryll is 69$
I have stone 400 g 00963945433653

wow didnt even cover red beryl
Be is toxic I've been told, So how are you able to pass several chunks of Be metal around the room?
Stupid is my guess
If it is pure Beryllium, I won't hold it unless under gun point. The cube must be Be alloy.

No panthers in Brasil ! Jaguar perhaps .
Just got myself a large 135 gram sample of the stuff.
I’m actually buying red beryll
Be
sound travel fastest
sweet taste
toxic
uses
transparent tube in x-ray.
Beryllium laser
gemstone
emerald
about 4 times as big? looks more like 100-times-ish lol

lol 13k views. might be too late now but i wish folks would wake up.
(tyvm great video!)
What do you mean by that?
And it is carcinogenic...
the Be dust is only...

Carcino genic? So it's Italian haha you should be the real one
Too much introduction. Otherwise, very enjoyable.
Say their names.
