Cracking a Geode 

It's amazing, when he broke the geode open, strange music began to play.

You can tell that the kid in the red jacket really doesn't care😂

Who else is here cause of instagram

rip geode like a bagillion years ago - 2015

I used to mine geodes and i gotta say i havent seen anyone do such a bad job at opening one. Congratz you just destroyed something that took thousands of years to form.

I also have a better way to open a geode. (If you cant tell, I'm a geode fanatic). -Use a hammer and chisel. -Look for a crack by submerging the geode in hot water. -The air will expand and leak out any cracks. -Place the chisel along the crack and start tapping it with the hammer. -90% of rattling geodes already have a crack -If you find no cracks, start chiseling a groove around the circumference of the geode. -Keep chiseling the groove deeper until a crack forms. -Try to direct the crack along the groove with the chisel -That should break it into 2 perfect halves.

Bet the janitor was pissed

i would pay 10000000000000000% attention in that class

The background music is too loud, can't hear what people are saying.

Its amazing these crystals see the light after million years

awesome video!!! cracking the geo + music = top drama ! wish I had a teacher like that. Thank you so much for sharing.

This is a great lesson for those who wish to have a clogged sink drain

My parents went on a rock and mineral society hike in Alaska when we lived there in the late 70's and found a bunch of them. They where all solid, duds

wow. that was awesome. I have always been fascinated by minerals and gems. heck, i have 5 geodes of my own. that was a very cool video.

I'd rather take this class over Spanish...

I've seen them opened with a chain and a lever. The chain is wrapped around the geode and tightened by the lever until the pressure fractures the geode under the chain. It's like breaking a piece of glass by putting a force on a very small area along a line. The glass breaks along the line, the geode breaks right along the line under the chain. It only works with reasonably hollow ones.

For next time, try placing a cloth between the rock and cutting board, it wont move as much, won't lose debris and is easier to collect. Washing, use cheese clothe and save the plumbing! Fun video!

Wow gems are so interesting they take thousands of years to form and we just...look at them intresting

the slow motion part was so suspenseful lol

what a kind teacher.

That 2 Balls on paper have blown my mind!

What an awesome teacher! I loved watching

I love this!!! What an awesome teacher!

What a great teacher.

I have access to a saw so I no longer use a hammer because they tend to shatter as you demonstrated. Great video!

Love the dramatic music!

It's not the part of smashing the geode with the hammer that I did not like, But the fact that the teacher let that student wash all that clay and minerals right down the drain.

it is ausome watching the prospecting of gem stones, and i just watch the cutting open of a geode, simply fasanating

The music is coming out of the geode. Everyone knows that once a geode is broken open, cinematic music wafts out.

Okay so for everyone who came here from Instagram or Snapchat please read. This is Mr.Boal he is an 8th grade science teacher. He’s actually really nice and good at his job. This was made for our ecology club! We go around and pick up recycling and learn about different things about science 🧪 it’s a great club for anyone!

the music is really annoying

why not use a rock hammer? and i recommend light taps in a line around the geode to form a precrack it helps

Who else came to watch because of INSTAAAAGRAAAM

That's alotta damage!

That kid never got his chance...

WOW that must be cool inside

Instagram clickbate?

That WAS a nice geode

I just wish people would not use such loud music in youtube video. Dramatic effect is fine, (within reason) I like to hear what is being said. At least 80% of the youtube videos I have watched over the years, blow the video with music.

Forget my actual science teacher this is mine now

with great power comes great responsibility

The slow motion did it for me.

I found a better way to determine if a geode is hollow or not. -First, get the density of the geode in g/cm^3 using a scale and spill tray. -Divide the density by 2.65 (the specific gravity of quartz) -minus that decimal from 1 and multiply it by 100% -*That is your exact hollowness as a percentage of mass* Anything more than 10% is usually worth keeping. OR -take the volume of your geode and multiply it by 2.65. -That's the mass of the geode if it were solid. -Minus your geode's actual mass from it's "solid mass". -That gives you how much mass is missing. -divide the missing mass by the actual mass. -multiply that decimal by the geode's volume. *-The result is the exact volume of the inside cavity of your geode!*

I like the paper holes with those two balls more than the geode

Love the music!

Hey, I'm glad I joined! That was so fun, can't wait for the next one!

Omg I want this guy as my science teacher

Wow this is fascinating, I love it!

Somebody call the janitor!

its pretty neat how he breaks the geode in almost 4 equal sizes :D

music too loud!

Wish he woulda been my teacher. Like the paper thing.

your a good teacher

step back Superman it's kryptonite

He cracked open an ancient turd

Interesting video, it shows how cracking the good rock. Interesting which place to see the weakest part. Know I know what tool I might use for such as this teaching point. Thanks for sharing your video with us. God Bless.

I learned something from this video! Shake a rock, if it rattles, it's a good probability it is a geode! But, WHERE to locate these rocks that shake? That is what I want to know. I live in Florida, and we have a lot of limestone here....

great video !!!

The kid at 3:08, red shirt.. he was like "yeah, whatever"..

Maybe saw it open with a diamond circular saw blade if you can put the rock into a vise first, and if the saw can be properly set up to do the job without the rock shifting around underneath.

I saw this on an Instagram post and it said it was from space 😂

Rule #1 of breaking open geodes: Never do it on a floor

did he just killed a dragon egg??

Thats the sound of a teens heart breaking.

The Song at the end... i thought the LA Beast would enter the room...

4:55 umm yummy, BBQ😂😂

breaking geode open make me giggle

Not sure if the 4-way split was what you had intended. For best results, I'd recommend using a soil pipe cutter. Normally, geodes won't "rattle". Rattling on the inside may mean the crystalline formations have been damaged. Instead, knowing what to look for in a given area is your best bet. Geodes normally have a chalcedony outer shell which give it away. And although many of them are hollow, they may have crystalline formations that almost fully make up the center dampening the sound. The rust/iron oxide is hematite. I'm not really sure what was said after the approximate 3:04 mark due to music output being too high. By the way, where was the geode found?

cool! Thanks for the lesson!

What if he released an ancient alien virus cracking geodes.

Rocks really rock !

A geode must be CUT, not SMASHED WITH A HAMMER!! That geode took at least 1000 years to make.

The inside of that geode looks like rice crispies. 😂

i can't believe he used a dyed geode slice!!!

This scientist is most amazng. I say scientist not just because he wears the classic white lab coat but his obvious mastery of the science of hammers & rocks shaped like lips early in the video. The way he demonstraited the theory of 'putting force on things' with the spheres & paper is Nobel Award worthy science, although I was worried he'd burst into flames by such a brazen demonstration.. He later went onto write a paper explaining how in fact the Geode was an actual fossilized dinosaur turd.

Uhh why are people hating on him for cutting it wrong? I don't think he has a diamond saw blade just lying around.

Who came from insta

'can i hit it' 'okay ill let you have a chance' fucking smashes it open

the music sounded like weird science. hahhaa

New floor tiles , why didn't you use a sand bag or something to absorb impact.?

Imagine he opened it and a alien pop out

he looks very natural holding balls in his hand

I'm here from Instagram

Imagine being the teacher or kid recording and getting 146k views on a video you put on youtube to share with a few people or something like that lol

The guy at 3:8 really doesn’t care lmao 😂

Mr. Boar reminds me of this crazy guy Dennis at this old dive bar, Dee's Cafe we used to hang out at back in the 90s. This guy used to call my Powder Keg. I never knew why. That geode looked like a rotten cantaloupe when you busted it. I had a cool science teacher many, many years ago. Actually, I think all my science teachers were cool. Also- what kind of jackass would give this a thumbs down? The kind that don't like to see kids enjoying science with cool teachers. Jerks. Keep smashing shit, Mr. Boar.

Are you, per chance, a heavy handed gentleman?

I was told that what’s inside this rock is disturbing

he did say rust inside right? that would mean iron oxygen and water were trapped during formation correct? so if left alone under pressure for lets say another million years what would happen?

Love it!

Are the rounded crystals the beginnings of what would have been pseudomorphs had conditions permitted?

I love Crystal geode

That’s the guy from the movie district 12.

You demolished it dude! What a shame.

HOW DOES AIR GET INSIDE? IS THE AIR COMING THREW THE ROCK? IS THERE ALWAYS GOING TO BE AIR INSIDE? HOW LONG DOES IT TAKE FOR THE INSIDE TO FORM THE CRYSTALS? HOW DOES IT DECIDE ON THE INSIDE COLOR? WHERE DO YOU FIND GEODES? THANKS FOR SHARING.

I’m not lying this was my 8th grade teacher

I believe this was part of something living, like all rocks. He said rust, I think it's dry blood. There were Titans/Giants beings, and animals. I think different parts of them crystallized. Research Mud Fossils.

I wanted to see what it looked like with the rust washed away.

the kid in the ohio state hoodie does NOT want to be there lmao

R.I.P geode
