The Story of Opal

[@brianm9962]

Curiosity show, you are still teaching me wonderful new things after all this time.

[@CuriosityShow]

Excellent, thanks. We learned a few things doing the segments as well - Rob

[@Billo1281]

What a great TV show! Wish we had this when I was growing up in the 80’s in the U.S.

[@johndaarteest]

I don't think there's anything like this now as a TV programme that's shown for children anywhere in the world. What a great show.

[@NoahSpurrier]

Great episode from a great show.

[@scottcantdance804]

This was really cool to watch... I'm in America and hunting for petrified wood is my hobby. The days I find opalized wood are always exciting.

[@marcello234]

Strong pangs of nostalgia as I watch this. I used to LOVE watching Curiosity Show in my pre-teen years & brought about a life long love of science. I'm also enjoying the "analog" demonstration of how the Australian landmass formed, nowawadays of course,it would be done on a computer.

[@SteveFrenchWoodNStuff]

Very interesting. Thanks for sharing the video.

[@CuriosityShow]

My plrasure. Lots more at kzbin.info Spread the word - Rob

[@r1w3d]

I'm American, I know opal comes from Australia, I knew opal is silica, I understand how fossils are formed, I had not even the slightest thought that all of them come together as a singular... I'm smarter now for knowing what I have just learned but here as I type at 3:33 am I feel ignorant for not knowing previously. Thank you. I wish I knew of this show years and years ago but I do greatly enjoy learning new things and I can share the things with my kids.

[@CuriosityShow]

Many thanks - we learnt a lot doing the show - Rob

[@revieweryoho5028]

Awesome! Thank you!

[@krakenpots5693]

This show is like tje aussie equivalent to "c'est pas sorcier", a science show we had in France.

[@andreaandiandi4061]

love love love it!!!!!

[@SanjanaRanasingha]

Thank you Sir Rob

[@misterglod8893]

What a legend

[@garyp4374]

what a gem of a show

[@tendarb]

I see what you did there... ;-)

[@yummyyum4626]

Inspiring and relaxing.

[@MileyonDisney]

That was very interesting. Thank you!

[@chlorophyllheart]

A fossilized prawn! Wow. I've seen a skeleton turned into opal, but I didn't think flesh could become opal.

[@daveninjaneuro7089]

Awesomeness

[@dexlao9434]

Who is that one disliker in every videos on this channel

[@redeyestones3738]

What a great video! Thanks Phil, @TheOpalMills for the suggestion!

[@zanescents3986]

This is perfectly wonderful

[@DJay0111]

Cool video. Very interesting.

[@SanjayKumar-qh5hl]

At 5:00 Why are the opals stored in water??

[@CuriosityShow]

The structure includes water, and opals can in fact dry out. Ethiopian opals can be told from Australian by putting them in water for a while. The Ethiopian opals take in so much that they turn 'milky' until you dry them out again - Rob

[@joeo6110]

Question do and have the fossilized or opalized humans ever been found since the whole opalization process can happen quite quickly I've been informed in a recent video ?

[@CuriosityShow]

Never heard of that. I think we have not been around long enough. You do get human skeletons 'fossilized' in stalagmitic concretions in caves, but that is a much faster process - Rob

[@1.4142]

None have been found. The parts of the world favorable for opalization of fossils to occur are too few and far from ancient human activity.

[@choboibigly6565]

Guess we gotta make some human opals for the next set of sapient creatures fellas

[@UnitSe7en]

@@choboibigly6565 Imagine the Crystal Skull conspiracies...

[@RustyRollers.]

Wow that was cool to know

[@Maninawig]

Wow, so many lessons in this episode. Though I wonder if all the fault lines make Australia prone to earthquakes? (Republished because of a stupid troll ad)

[@CuriosityShow]

Parts of it are, certainly, but the LHS of Australia is very old, the RHS more recent and prone to quakes - Rob

[@Maninawig]

@@CuriosityShow it's good to know as I've always wanted to visite, but never experienced an earthquake. I think knowing it might happen can alleviate some of the panic.

[@UnitSe7en]

@@Maninawig I think you should seek professional help for your irrational phobia.

[@Maninawig]

@@UnitSe7en fun fact: first aiders are taught how to deliver babies. Despite that, most panic the first time they have to actually deliver a baby... Not because of a phobia, but because of trying to think critically during a new experience...

[@tendarb]

Yes, we do have earthquakes in Australia, although not all that regularly. We mostly have small tremors, below 4.0 (a few a year), but occasionally larger quakes causing significant damage and death do occur unfortunately. I'm in the east of the country, and yes, I've felt a few of them over the years. You get used to the small ones, but the bigger ones make you stop what you're doing and pay attention!

[@Eduardo_Espinoza]

Cool

[@thesisko2065]

When I pass, turn my body into opal. xD

[@rahuldoshi1376]

How did u had so much knowledge back then in 80's ?

[@foxdown]

I really really miss kind this informative documentaries. Old documentaries are not about lions or penguins

[@UnitSe7en]

Not a documentary. This is a segment from a children's television show which was aired in Australia in the 80's. The channel has more.

[@foxdown]

@@UnitSe7en yes I am a millennial I understand that kind of things thank you 👍

[@U014B]

So does that mean opal jewelry is non-vegan?

[@CuriosityShow]

Certainly would be if it is opalised remains of sea creatures - but i guess eventually all molecules get reused by something - Rob

[@UnitSe7en]

Look at all that climate change, eh?

[@TrapperAaron]

It's amazing. Now imagine instead of it happening over 100s of millions of years, imagine the consequences for life as it happens over course of 100s or 1000s of years.

[@MAC...007]

I think time has been over quoted. Not millions of years but thousands. Thanks to freemason science for over doing it !!!

[@jlvmedia]

M AC why because you believe the biblical timeline?

[@choboibigly6565]

Earth is old

[@tsopmocful1958]

It's the "Curiosity Show". Not "Creationists Being Slow".

[@MAC...007]

[@b.r2715]

He didn't mention that the whole Earth was covered with water at one time, and not millions of years ago either, still a good video 👍😁

[@CuriosityShow]

Thanks. Curiosity Show was a national science program for children featuring Dr Rob Morrison and Dr Deane Hutton. It was made in Adelaide, South Australia and screened nationally in Australia as well as in Europe, Asia and Australasia (14 countries) from 1972-1990. Deane and Rob intentionally used everyday items around the house (like old cans) so that children could repeat the demonstrations with materials they had to hand. In 1984 Curiosity Show won the Prix Jeunesse International, the world's top award for children's TV programs. Rob and Deane are steadily uploading segments at kzbin.info Why not subscribe?

[@jamalnasir5648]

So when exactly was the whole earth covered in water according to your timeline?

[@tendarb]

That was a Kevin Costner movie wasn't it? ;-)
