 Hello everyone, my name is Alberto, and I'm with the YELV 2021 Intern team and my project is about rocks and stones so I'll be going around the Bay Area and collecting rocks and stones and Showing you guys how they look and how they form now I'm specifically on the hunt for a rock named a geode which looks something like this and Inside of the geode. There's a cavity filled with quartz or Better known as crystals and it looks pretty cool. Some will also show you guys where to find them Now before I go rock hunting some of the ways to identify if a rock is a geode if it kind of looks like an egg because They usually take forms of a sphere and another way to identify if a rock is a geode It's like hollow because usually geodes have cavities Inside of them, so if it feels light and it's hollow and it's also a sphere and it's a pretty good sign that it's a geode All right guys, so I made it right here to this hill Hopefully I could find some some rocks here so There's not a big variety of rocks like actually kind of underestimated how like Much stuff there is but I'm gonna try to find a rock Okay guys, I just stumbled upon this rock Now doesn't really look too special There is some like minerals in it So might be granite Yeah, I'll keep looking I really want to find a geode When you crack it open, it'll have a bunch of crystals Well, I'm at this is the rarest But there's also the most common one is white quartz. It's usually has yellowing sometimes See I'll keep looking so far it's been like an hour and 30 minutes. I haven't found anything So I'm gonna have to travel to a few locations Okay y'all Right after I found the granite, I actually stumbled upon some sandstone See right here Sandstone, so that's pretty cool Which means that it's There's a good chance we might be able to find a geode Yeah, I've got to keep looking All right guys, I actually think I found a geode. There's like a lot of rocks here Right here is a geode. I think I mean it matches the description looks like a quartz one So I'm gonna check it at home and try to crack it out and see how it looks Yeah Alright guys, I found another rock right here Okay, I'm looking at it and I actually looked at the handle. I'm not sure what type of rock it is But I'm gonna make sure to check it out when I get home Okay guys, so I think I found a good spot right here. There's a couple of rocks Nothing really interesting. I mean there's this one. Actually I think it might be a geode. I'm not sure It's too like dusty to tell. I'm gonna check it out, but it feels pretty hollow. So Good chance it might be a geode There's also a couple other rocks, but they're not that impressive Okay guys, so here are the geodes And right now we're about to go like crack them open Okay guys, so here are the geodes Now we have three ways to get these open One is with like a circular saw So you get a clean cut The other way to crack open the geode is the sock which is like a classic method And then the third way is Hitting it with a hammer Okay, I got the sock here And I got the geodes, so now I'm gonna put them in Okay, so I'm gonna go and try to crack open the geodes Okay, so now we're gonna see if Okay, so now my brother is gonna go ham on it Okay guys the sock method it received a lot of damage So everybody see if it worked or not Okay guys, so only one of the geodes ended up opening As you can see right there These other ones they're built like steel, so we're gonna have to go with the second method the hammer Okay guys, so now I'm gonna go and proceed with the hammer All right guys, I forgot about another method method for the rock So I'm going to go ahead and hit it with a rock Okay, let me try this one's a pretty heavy rock as well. It's like hefty Okay Method four isn't working very well, so I think I'm gonna have to go ahead with the hammer again Alright guys, I've managed to Okay guys, so here are the geodes is how they came out So now we're I'm gonna go back home and fill in with better lighting so we can see them So we're back and here are the geodes up close so we have two variations We have the quartz variation and the calcite variation Now the quartz variation has a lot more crystals So it's a lot more solid And they're a lot more bigger Now the calcite geodes are a bit different as you can see they look a lot more sugary And there's a lot more sparkles in it And for reference here's some salt and sugar Now here's a comparison between the quartz geode and the calcite geode They look almost identical Except one of them has more sparkles than the other Some of you may be wondering how do geodes form? Well, when rocks form sometimes they might have small cavities These cavities are ideal for geode growth because when water passes through them All the small minerals get caught in the cavity causing crystals to start growing Geodes could take thousands or even millions of years to form Depending on the size and the conditions of its environment Speaking of the environment here's where I found the geodes along with its coordinates Here's the location seen through google maps as you can see there's a lot of rocks and a lot of boulders So it's pretty much matches where you'd find a geode Now before I show you some of the resources and books I use I want to show you this website called Hoopla So you basically log in with your library card and password And you get a whole selection of a bunch of stuff from your local library Which is pretty neat Here are some of the books and resources I use to do my video and to do some research But yeah everyone, um, that's about it. You made it to the end of my video So I hope you guys learned a thing or two and enjoyed it Thank you for watching
