This video made me think of a trick I learned long ago: Bending a single stiff and brittle crystal without breaking it. Even though it sounds and looks awesome, and is so easy to do, I cannot find any mention of it on RUclips or Google. So maybe it would be a good one for you to do. The trick is to get a long and thin salt crystal, grab either end with one hand, and bend while under running water. I suppose submerging it in water might also work, but maybe it needs to be flowing quickly? It works because cracks always start at the surface; so if the surface is constantly being dissolved away, a crack cannot start; and so instead the crystal deforms into polycrystals that change crystalline axis as they go around the bend. I only had salt crystals ~8 x 3 x 2 mm , but maybe you could grow much longer ones for a more impressive demonstration.
It's not just thickness, its thickness to length ratio. For example, tectonic plates have about the same thickness to length ratio as that sandstone slice you just bent, so it stays elastic. That's why earthquakes happen, because plates keep skipping as they slide thorough each other. Note that this is unlike what you last described since that was plastic deformation, which forms ridges and mountains and what creates earthquakes is elastic deformation like what you did with the sandstone.
@@patstaysuckafreeboss8006 LOL I had to look up what the hell you were talking about. Never seen an episode of that show. I guess I should watch it so I don't accidentally use a pun that they used so I don't offend your delicate sensibilities.
Great video, I never thought about this until now, but every rock tells a story, it will be really interesting from now on to see a rock and think about how it's basically a fossil that formed over millions of years
Yo Average Art Kid It’s not an r/wooosh? I was making a joke about his comment, that I understood. It would be a wooosh if the point of his comment was that he was calling it rock bending instead of earth bending. Since he wasnt, my subsequent jokingly mock of him does not qualify as an r/wooosh, but good try
I really like the explanation of the experiment. Most people would just do the experiment but never go into scientific detail. I'm always interested in finding out why and how things work. Great job!
I think the slice of sandstone was more "pivoting" than bending. To test the bending, you should have set it between two hard objects, as you did for the glass rod. Because if you look closely, you can see that it pivots around a point where it's touchin the rock on the left (which is not flat), and the "spring motion" is created by your hand that's holding it so it goes back to the original position. I guess it does bend (actually the last test you do when it breaks, the slice seems to be held in place firmer, and there is less pivoting), but this pivoting motion makes it hard to differentiate between bending and pivoting.
I agree, sedimentary rock is briddle, thats all. So before it would bend it would crack at the point with most force because the sandstone grains are not bendable themself, they are very pourus. Its like with bread, bread itself is only elastic as long as you compress it, if you pull it outwards it breaks and does not go back to its original form. And elasticity means something goes back to the original form. Well if you rip bread apart it does not go back to be one part but now you have 2 pieces.
I'm laughing right now. My masters thesis is on the flexural strength of various brittle rocks for a stone tool study. 2:16 is exactly how I am testing my materials. And I've been reading extensively on fracture mechanics, stress, strain, and elasticity. Very apropos video for me.
Awesome video!! I feel this video opens the door for you to explain Young's Modulus, Hooke's Law, and resilience in objects. Also, I forgot but there is a term for a material that lags behind when a force is applied to it.
when I studued material science many year ago, we ran an experiment with a stone cylinder. We put the cylinder under very high hydrostatic pressure, then squashed it into a spherical mold. In less than an hour, the cylinder flowed into the mold, making it spherical. This showed how brittle marerial can be formed plastically, by preventing it from having tensile stresses. Another thing we learned was that materials get more brittle when they are loaded very quickly. We dished a mild steel plate by loading it slowly. When the same test was done very quickly, the steel behaved as a brittle material, and a flat disk was punched--with no evidence of plastic flow. This is why a slow bullet dents steel, while a very high speed bullet punches a hole.
I'm pretty sure by this point he's bent Earth, Air(Bermoulli's Leafblower). Fire(Infinite Tempurature, Focused Laser Beam), and water(With the charge from a Van De Graaff Generator). This is just rounding out the last of his skills. The *Avatar State* ...That's what I'm waiting for. O.o
Another way to bend even thick pieces is to heat them up to really high temperatures - rocks also behave pretty much like glass and doesn't have a fixed melting point. It become softer above a certain temperature and is then gradually turned to a liquid lava as the temperature rises further (usually temperatures of about 1000-1200°C depending on the type of rock, will make it soft and easy to bend without melting, haha).
I suspect much portion of the "bending" comes from the rock not being perfectly fixed between your hand and the supporting surface below. Please, repeat the experiment with a much better fixed rock. Use a vice or something. Or you could use the thin layer of rock as a bridge and push it down in the middle. That would solve the fixing problem.
Even if you talk only about a few years of compression, you can still see bent rock...for example who hasn't ever seen a table made of marble, which is a few years old? Did you notice, that it is slightly bent in the middle? Well this isn't an optical illusion. This is real and it's due to the continuous action of gravity on the table top and of course its acting most in the middle because at the ends it is supported by the table's legs or carrier columns..if you haven't ever noticed this, try to look closer when you next time see a table made of rock in a garden or park
I did not look as it was bending. It actually looked like that your hand couldn't grip the rock too strongly to the rock beneath, so the rock was still solid but going downwards and then upwards when you release the hand that was "bending" because now the only force is the one that your hand is making by pressing the rock to the other one
9:40 another example of this is in parking lots, for example i was once in a six flags parking lot and in all the spots where the cars' wheels /tires would go there were very noticeable divots, a few inches deep
Cool video. I saw I video of a ignition spark, going from a near vacuum to a full atmosphere. That should be pretty cool to see in that Phantom cam of yours.
A good way to explain this is with a pink eraser and bend back and forth until the outer part starts to rip, it happens really slow and is quite satisfying to watch
