I recon thats one of your best yet Ian. :woohoo:

Thanks Doug - I thought it might come across as "boring" so I appreciate your support ;)
nice. commentary. :lol: :lol: :lol: . ian f.a.f
it had a touch of David Attenborough about it lol..
Dryer than a nuns crotch - Like a 1980's Open University Course program - I laughed my cotton socks off the whole way through. Brilliantly put together - nailed it! :-)
Liked. B)
My only suggestion would be to look into removing background noise from your Mic when doing the narrative voice-over.
I'm super-picky about stuff like that though, so don't consider it something *everyone* will dislike. Most people are sane, and don't care much about the sound unless you have a small hurricane blowing through at the time You recorded t, and can't actually do a damn thing about it. Then, they will bitch in their legions :P
Interesting comment Ali ....
I deliberately left the background noise "in" as some other people said they wanted to hear the "cave" and not the "blasted music" I put over the top.
I dubbed the narration on afterwards at home.
Thanks for pointing it out :)
Ian
You can't please all the people, all of the time. I would consider me a minority.
Good video Ian. Reminded me why I'm not too enthusiastic to go back there. :whistle:

wtf its a cracking little place to play.
ian. dont listen to anyone the vid was bang on the money :kiss: :kiss:
Great video Ian. Think I definitely need to cut my pie intake down by about half before I can fit down there!

its not as tight as it looks there just making it look hard.
if les-w can get through there anyone can :whistle: :whistle: :whistle: :whistle:
Excellent video. Like the atmospheric dripping effect and the commentary - It's a lot better than music...
Not sure about the "Calcium Nitrate" and "Zinc imbued calcite" - The latter is pretty water soluble and so unlikely and the latter might be possible, but without a spectrophotometer analysis I wouldn't like to comment. (I was a chemist in a a prior incarnation...)
Dave
Thanks Dave :)
It was a chemist that identified the calcium nitrate (a salt) and I wouldn't know the difference between calcium nitrate and sherbert. The "zinc" was a guess- we know it is in there and we know it offers a "browny" colour when it interferes with calcite.
.... call it "theatrical licence" lol ;)

Ian

Jimmysavillite...?
how old is the calcite that is being interfeared with?

Perhaps we should ask a geologist ? ;) ;) ;)
Calcium Nitrate is Saltpetre (one form of it anyway). It was worked from the cave earth in the American mid-west and deep south to make gunpowder. It only occurs in totally dry cave and will disolve immediately in any water...
There is unlikely to be any Calcium Nitrate deposited in any UK caves...
"A Geologist says..." :whistle:
I thought saltpetre was "Potassium Nitrate" ?
... so says a total "n00b" :huh:
Calcium Nitrate.
https://en.wikipedia.org/wiki/Calcium_nitrate
Potassium Nitrate.
https://en.wikipedia.org/wiki/Potassium_nitrate
A number of compounds are referred to as saltpetre. I ran into it a few years ago. As usual, it's Wikipedia, so it's not guaranteed accurate, but it ties with what I remember, though that in itself is reason to check some better sources.
The saltpetre I know is potassium nitrate and is used in the bacon curing process as well as an ingrediant of gunpowder, it is very hygroscopic and would be in solution in a wet cave, for what it is worth, I think the substance in Ians video is Gypsum, or calcium sulphate which is common in caves, and forms when sulphuric acid reacts with calcium.
:silly:
....and bearing in mind Doug has a) Definitely cured his own bacon, and b) more than likely made his own gun power. The Wobbly Helmet award for all time knowledgeable boffin goes to non other than our very own Doug "Goon-Suit" Thompson! ;-)
Honoured i'm sure. :dry:
Saltpetre is indeed a generic name for various nitrate salts.
The constituent of gunpowder is Potassium Nitrate and the calcium nitrate extracted from cave earth in the US was processed into Potassium Nitrate by reacting it with potash from wood ash. The process was very complex and used the waste products from the evaporating fires to react the calcium out at a later stage. Very efficient, and normally carried out by backwoods men to supplement their meagre living.
There are several good books about it and if you are going to the US any time, particullarly to Tennessee or Kentucky there are several caves (including Mammoth) where the extracting aparatus is still in place.
Calcium Sulphate (Gypsum) is quite likely in limestone caves, particullarly when it is associated with mineralisation (lots of ores are sulphides). B)

he is know to most of us as doug "the mad scientist" thompson.
i remember haveing a conversation with his a few years ago about running a car on hydrogen gas, and his reply was" oh! yes i was experimenting with that back in the 70s
i almost blew the bloody house up. i was talking about a car he was trying to run his bloody house off it.
like i said MAD SCIENTIST :woohoo: :woohoo: :woohoo:
