I wish you would stop "Powerpoint Slide"ing your videos. When you post the words you are saying as part of your video... and then say those words, its redundant. If I wanted to turn on Closed Captioning, I'd do that. Rendering the words and then reading those words is useless. I'm in meetings all day and when a person is saying the exact words that are on the screen as the words are on the screen is terrible. Stop the Powerpoint Slide Video style. PS: i like the content and the presenter, just not the delivery method.

The Virgin Valley Opal Mining District in Nevada has Black Precious Opal fossils too. Usually Twigs, like this one: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yAhmBnVOFNE.html , to trees and rocks, but also animal bones and casts. I also have a Facebook Group for Swordfish Mining about the valley and its mines and gems. You can even pay some owners to mine their claims. (How about the little glass beads without any inclusions in the ice cores?)

The one thing this channel lacks is more visuals for the things they’re discussing. Sometimes what they’re talking about would be awesome to see, but all we get is text on the screen of exactly what they’re saying. I think adding more images or even video clips of what you’re talking about would take these videos to the next level!

@lancewedor5306 Год назад

I think this a major flaw with the presentations. I can hear what they say, so amplify the topic with visuals that are pertinent.

Fun fact: One thing many people don't realize is that if you're wearing an opal ring, and you reach into a freezer, your opal can break, and sometimes even shatter. That's because of the water in them. Water expands when frozen. Opals are very fragile.

frogster eighteeng does foam on freshwater lakes also contain diatoms? I have noticed that, on the small lake in NE PA where I live, different times of the year will have (slightly) different foam form when strong winds blow, but I never gave it enough thought to try to look anything up, but seeing your comment piques my curiosity, and different diatom growth at different times of the year could explain it.
