- Grinding down flint/chert by hand - how hard can that be?
This is a fossil that I picked up on Portchester shore about a week ago - on examination of the naturally fractured face of the rock, I thought I could see some traces in there that might be indications of soft tissue fossilisation. In this video, I will try to grind it flat to get a closer look... - Навчання та стиль

Some people go through life without question or inquiry. Then you get people like Mr Shrimp. Keep your mind open and keep asking the questions that dont need asking.
I love the randomness of this channel,, videos about people’s interests are so cool especially when it’s about something I would not otherwise look into, great video!!
maybe check out cody's lab... a little more sciency, but just as random
@@MrMCKlebeband bet his accent isn't as lovely. lol
Agreed, I came for the scam videos...I stayed for the Atomic Shrimp.
You did that for 6 hours!!! Wow
Yeah, it was like an upper body workout
@@AtomicShrimp i would have already making some grip that i can attach that thing on an drill ... in like 60 seconds :P
Grinding away for hours...using both hands...oooh, I say!

Sorry, bad joke...I couldn't help myself...
@@kimvibk9242 saves me from doing it me old matey! Ha ho!
@venix20 I will make something motorised, but I didn't want to rush it
I was watching this with my 8yo son who said "this is the first interesting video this guy has done". He had so much to learn!
I love how diverse this channel is, I’ve never seen a bad video and find them all so interesting. Thanks Atomic Shrimp for getting us through lockdown.
So that's how congressman's brains looks inside. Fascinating.
Nah fossils existed at some point
I finally ordered a rock tumbler here in the U.S. Your video reminded me that I can't wait to polish some stones that I've been saving. I do wish I had a way to slice into stones. It's fascinating to see the internal "anatomy" of rocks and minerals. Yes, Rachel Bass, I enjoy the randomness of this channel. EVERYTHING seems to be interesting here!

Fossilization is the greatest record keeper on living things.
That's a really good point. Hope you are doing well!
@@g10118 thanks, I am.
Unless you don't believe the fossil record is accurate, like some religious people!
@@tincanblower 😂😂😂😂
That's true. I should have been fossilizing my family members instead of burying and burning them.
I find my self often feeling blessed having somehow come across your channel.✨🤗✨
From my side of the ‘pond’... THANK YOU VERY MUCH for what you bring to my various screens!💕
Interesting thing about fossils is how they are formed in different minerals. I’ve found many different types. If it weren’t for the soft minerals forming fossils we may not know about some feathered animals. The most interesting fossil I’ve found thus far was in clay. Upon some intense poking and prodding it turned out to be a fossilized Barrister who goes by the name of John Warosa.
Loving the JerryRigEverything reference :)
Thank you for taking my mind off of the obstructions and defeats of the day with this. I used to love collecting rocks and things when I was a child. Maybe I should do more. You've inspired me.
Hat off to you for grinding that flint by hand for hours! The 2nd stone looks really cool! It has been interesting thank you sharing this video with us. Making a pendant from any of the stones would be great!!
Fossilised sea urchins are probably the most common fossil found on UK beaches. Any beach that has shingle and/or a rocky shoreline and you will often find fossilised sea urchins. Some can be really beautiful. Growing up we had hundreds of them scattered around our house and garden. Living only minutes from a West Sussex beach and my oldest brother being a geologist and palaeontologist it meant our house was rammed to the rafters with all my brother’s fossilised finds from wherever we ventured to search for fossils. Many years on and his own family home is just as bad, if not worse!!
That's a supreme privilege to find such a wonderful marker of our planet's history. I know for sure that if I ever find myself in the Northeast for work, I'll be poking around the shores for Meg teeth.
The reason for that very glassy texture is that flint (and all cherts) in fact have the same structure as glass. A "cryptocrystalline" structure, they call it. This is also why it is so useful for making stone tools--it creates very sharp edges when it fractures the same way glass does. You note the similarity to agate, this also has the same sort of cryptocrystalline structure! Thanks for the video
That's incredible patience, lad, you're the guy for the job!
This is possibly the best content to watch at 4 in the morning
Hahaha EST peoples unite! (And good morning!)
This is almost TOO apropos to my current situation.
yes, and at 3:39 a.m. as well.
@@g10118 GMT here - I have no excuse for a terrible sleeping pattern, but if I'm spending the night awake, this is how I want to do it 👌
Possibly? No
Definitely!
I think the urchin fossil would make an nice pendant too, if you could cut a slice of it and polish it up.
I love that your channel had such a variety of videos!
YES, so glad you got round to doing a video on this. I have to tip my imaginary hat in tribute of your patience, 6+ hours to complete. Now that's dedication.
Could you have attached it to a drill somehow? Maybe that could have sped up the process.
Anyway, thanks for sharing Mr Shrimp ✌️✌️✌️
Your channel is like a Kinder Surprise, you never know what you get, love it.
Nice one, We get similar pebbles on Chesil Beach 90 miles further along the coast. They look like gems in the surf.
Chesil beach is amazing. Did you know that fishermen landing there in fog could work out their position on the beach by the size of the pebbles? Pea shingle at the west bay end, with a continuous gradation to big cobbles at the portland end
@@AtomicShrimp im surprised he didnt reply, honestly. i dont have much else to say, but thanks for more informative content! this one clearly took some hard work, even if you did it to satisfy your own curiosity
@@AtomicShrimp yes, it is an interesting phenomenon of size ‘sorting’. As a matter of interest, there was a huge storm recorded on the 22/23rd November 1824 which breached Chesil and destroyed the village of East Fleet and flooded Abbotsbury, it killed many people in Chiswel, Portland and destroyed Weymouth Esplanade. A ship was out of control on the lee shore and the crew feared the worst but just as they were about to be wrecked, a big wave carried them up onto the top of the beach and all but two walked to safety. The ship was later refloated . About fifteen years later another ship was washed right over the top of the beach and landed in Portland Roads or Portland harbour as we now know it.
@@ciarangale4738 I had a call and had to go out, but I sometimes pick up the odd interesting stone and polish it up between my thumb and forefinger to rub the dried salt off, they come up quite nicely.
@@diogenesegarden5152 ah yep sorry about that one mate, truth be told after sending the reply i thought to myself, "eh its only been about half an hour, might just be busy"
i can't believe the fact that i'm still up at 4:50 am watching a video about a flint fossil
It's 3am for me. This is when I normally wake up, though
2:15am
This is far more interesting than I would have thought it would be. Thanks.
All that hard work deserves a like
Sea urchins are mostly empty in life too, so I would not expect to find a lot of interior structure.
Well the inside of seaurchins is mostly seawater but it is gelatinous. It is not empty it's just full of water which isn't great at fossilizing(if it doesn't has high concentration of minerals in it). But he I am just a random person from the internet not exactly the best source to use. Have a nice day.
When I say empty I do not mean empty as a vaccume but rather empty as in lacking structure.
I only have 4 You Tube creators on for "Alerts" and you are one of them. So glad I found you. Cheers from Philadelphia, Pennsylvania, USA
We need before and after weights!
You need a motorised glass turntable, and arm with a stepper motor rotating the stone.
It’d be an interesting construction project on its own!
Petition for you to start reading audiobooks and hey, you might even get sponsored by audible!
Love from Florida as always. Happy holidays to alll!
Your arm must be like Quagmire's after all that figure of 8 action
How you find time to do this amazes me sir! - I barely have time to scratch my arse most days with the pressure of earning money and family - Thank you 👍
Really loving the variety of content. As a fellow renaissance man I find your hobbies very interesting.
You're so dedicated to this work and I love it!
I made an audible noise of joy when this video popped up
Same here.
The small child in me wants the next video... NOW! You are too good, Mr Shrimp 😉
Amazing dedication and patience well done
Thank you for doing these things Mr. A.S., so we don't have to! 💚
Your channel is amazing! Keep up the good work!
The problem with sandpaper is that it wears down quite quickly when grinding hard material, probably the reason why your surface looked to smooth.
I think a diamond plate would have been much quicker in this case.
Atomic Shrimp: Laps for 6 hours.
Kiwami Japan: *heavy breathing.*
Mike, you might try picking up an inexpensive palm sander. They can be bought for around $25-30 bucks. I wouldn’t go with a belt sander bcz it would tend to leave lines in the work and they’re more expensive. A palm sander can also be used to vibrate forms for small concrete or plaster projects, very effectively.
Thank you. Great video. Greetings from Dimboola. Looking forward to the next video.
It's super, all by hand, like that. It did look good.👍👌
Always interesting and thought provoking. I have wondered about the insides of fossils I have picked up. Thank you for that.
i’ve been loving these fossil & mudlarking videos
Seen some very pretty weapons made of Flint,and surprisingly well shaped.
Thankyou for showing us.
Looking for random biology, geology, and much more this channel most likely has it all!
Why can't school be like this?
I could have watched you grind down that fossil in real time, love the channel, love the content. Keep em coming!
6hr ASMR experience
Man, you really just are the coolest!
Thinking of our forefathers who grinded and polished flint axes against simple sandstones. One single axe took 45 minutes to flintknapp but needed 40 - 100 hours of grinding :O
Yeah, also, some of the jewellery and decorative stuff carved from jade, carnelian, etc. Just amazing to think of the work that must have gone into it
You sure got alot of patience!
That closeup looked like a cosmic photo
I tried to polish limestone fossils before and it was easy. Never thought flind would be so much harder. Great video. Thanks
Yeah, limestone is about 3 on the Mohs hardness scale (with a deeper groove at level 4)
@@AtomicShrimp oh, now we know what the letter board reference is! 😁✌️🥧☕
Deeper grooves at a level 8......nice!
Great video!
The fossil looks beautiful after your grinding!
You maybe want to have a look at the meditative activity of Dorodango, creating a shiny ball just out of mud from your Backyard.
Mythbusters polished a turd 😁 IIRC it was in a ball shape at that point
that jerryrig reference took me by surprise
As random as it gets and I love it
There are special sanding machines that use a strip of sandpaper on a device that kinda looks like a defibrillator handle. It's mostly used for sanding large areas a little bit (like plaster on walls before painting), but you can also use it to take away a lot of depth on a small area. Afaik they are quite cheap, so if you want to continue with this idea you could get one and save lots of energy.
You have the patience of “Job”... I would’ve given up and found a sanding disc table. LOL
Even tho its just rocks and flint- the urchin still looks really cool
'...after hours and hours and hours of grinding we're still probably only about half way' -- Also a Sting quote, for entirely different reasons.
Nice fossil unboxing
2:17 Atomic Shrimp shows us his true power!
Very interesting, I like all your videos.
Hope your repetitive strain injury heals quickly! 😉 Hayling has a fair bit of flint from the packed flint-clay bands in the area from the ice age. Less fun when you're gardening, it's like concrete!
The outer layer might be calcedon. Sea urchin fossils are often made out of calcedon or have parts of it, that is made of calcedon :)
i worked in a destructive lab polishing metal samples and it was bad enough grinding stainless on 180 with a powered wheel. hats off that looks like a chore and a half.
what is a destructive lab and how do i get into one
@@ciarangale4738 some parts or materials require a more testing than nondestructive testing(x-ray, penetrant, ultrasound) so it would come to us. We cut it up and looked at the internal structure. I have no idea how to get another job doing it. I kinda fell into it because they needed help and hired on a temp. I ended up going full time as a lab technician. Look for quality lab technician.
Was looking forward to this, thanks for the upload!
Great video as always. Perhaps you could rig a used tile saw for your grinding machine thing. Diamond blades for it should cost around £10, probably less
Could you not have automated this process by either attaching the sandpaper or the flint to a drill bit?
Would've been astonishingly lucky to get internal structure preserved on the urchin given how squishy (technical term) it is, but the exoskeleton is so nicely preserved it hardly seems to matter - definitely going fossil hunting on those beaches some time
Damn, but you must have arms like Popeye now! Get the spinach (and nettles) on!
Also, the banded chert, might possibly look a little like a UA-cam play button?
Well there's that Italiamo Spinach & Olive Soup 😅
I knew this was going to take a really long time. Ive made a couple of hunting knives and grinding down the wooden shaft for the knife can take hours, well if you want it can take days using ever finer sand paper. interesting to see though
That zoom in at 5:30 looks similar to Hubble pictures of deep space.
Looking forward to a grinding disc - I think a series on "ground things" would be great!
Ground things from the ground
“Ground objects” like a play on “found objects”
@@__-bk6mm Noice. what about "Grounded"
I would personally recommend lapping the urchin before fossilising it, as it is much softer when it is not a rock. That way there is much less material to remove in the end.
^ This. Excellent advice.
Though, be sure only to apply the technique to a sea urchin. Got me into a bit of trouble that mistake did.
You can get a carbide wheel for a regular grinder (you don't need an expensive one because you're not grinding precision) and you can polish glass with cork wheels.
The lesson for me here is that this wasn't nearly as flat to begin with as I imagined it was. I probably should have run it past my diamond tile saw before starting!
Beautiful
15 years of polishing later Mr Shrimp 🦐 will discover a T Rex egg 🥚
Luv ur channel!!
Small matter, but the placement of the feet on the underside of the glass is quite good. My grandparents had a cutting board with only a foot in each corner, and it finally split down the middle both ways. (It was plastic)
Anyway, I think that kept the glass from stress fracture.
Fun vid, as usual, thought provoking. I've found stones the same color, and wondered what they were.
Looks like a Californian roll Sushi left in the fridge too long. :)
Hayling has some really interesting flints.
Great another video to continue my procrastinating
Somebody get this man a belt sander
Would you mind explaining why you used a “figure 8” when you polish?
It helps to even out any bias in the pressure you are applying to the workpiece. If you just go back and forth in one axis, you get a sort of rounded underside, not flat
Random as always and as Good as always. Thank you AS
This video is on fire. Flaming Moh.
When you got the sheets of abrasive and pot of water, I almost expected you to turn the flint into a knife.
You are amazing
Place electric sander in vise and let it do the work for you, my goodness you are a very patient man!! Take care.
I don't know your minerals there, but could your red pebble possibly be carnelian agate?
I feel for you..... Trust me, find someone with a wood lathe, we've all got diamond wheels for sharpening gouges, I swear it would have had that in 5 minutes !
Mr. Shrimp, chapo to you. Iam curious is there any hobby you don't have? Great mindset mister, I feel a bit shameful to only watch UA-cam videos, playing video games and read books. But you my dear sir are a legend.
Love it.
