Iron ball falls in sand (slow-motion).

[shoes121255]

Now how do we do this with space time to form a worm hole?...

[ViRoGmR]

BALLS OF STEEL?



[omgitslukky]

not dropped, shot.

[Zantaer]

dude, I think that's sand with like, water in it bro

[memberHD]

fucking magnets

[JunkyViking]

fucking tards, this is a filmed footage, not CG. wake the fuck up.

[EpicCookie7]

made with?

ps.loljk

[bernardweasley]

I wasn't expecting 0:05

[jelloofhell]

looks like a long stream of diarhea

[Megallean]

May I ask for render time?

[3hungrycatz]

that is so damn awesome

[drunksmokingjurkk]

its coool

[KisameSouth]

Id say water.....not sand lol. Other than that its a flawless scene bro. Id love to see the realtime version.

[dsavix4]

Interesting how much fine sand acts like a fluid.

[SneakingMoose]

its cool. but not realistic!

[orlanduce]

just think what would happen if a meteor 1 street block in diameter struck a desert

[TheFXGuy]

is that cg?

[123rickross]

....nvm not first comment

[123rickross]

Cool but that doesn't look like sand but I know it is and nice video…1st comment btw 

[JuniorProducer1996]

Chuck Norris just hit puberty bitches

were all screwed

[billelis]

im not writing this 2 argue im only saying that in my opinion this video has been made using krakatoa particle render and realflow and 3ds max or maya.this is my opinion cause i m using all that software and it just feels 2 me like u get the same result.i have 2 say if this is 3d then im amazed the detail is amazing

[fictionuk]

Some of you people are pretty ...naive I think the word is or just plain f*cking ignorant. Of course its real. Photoshopped...are you sure. A 3D program.....Its real, not a fake, not a photoshop image/video. ITS REAL

[TamaranthaArmyOnline]

beautiful!

[HEPPOCO1123]

Sugeeeeeeeeeeee

[robattrell]

That "particle" is a reflection from the metal ball on the glass holding the sand, it disappears because the ball disappears below the surface of the sand.

[ZirconCode]

This is AMAZING !

btw It's not fake. It's part of a slashdot article: "Researchers Discover That Sand Behaves Like Water" just read it and shut up =)

[ddillybar1]

wtf you're all morons, why the hell would this be a fake?

[niko011]

why are people debating whether this is real or not?

why would someone go through all the trouble to make a fake 'iron ball falls in sand' video... would have to be pretty sad huh...

[jabbaboy]

I think its a real video. But its no ordinary sand. Probably a fluidized sand bed created by blowing air through sand. makes the sand behave like water.

[n8daboss]

if it was fluidized, it wouldn't be as dusty or powdery!

[jabbaboy]

by fluidized it didn't mean adding water. particles in air is known as a 'fluid'. cheers

[Yeti22]

The little particle that disappears at 0:03 makes the integrity of the video as a whole seem iffy.

That said, that was freaking cool none the less.

[frolikinggiraffe]

It's called a reflection

[Yeti22]

Lol well done.

I can admit that was stupid ;) Granted it was like 4 AM. But well done, indeed.

[pierpointcove]

hahaha owned

[Yakeyglee]

oh wow, you're right. it probably is fake...but it's still some pretty good computer modeling nonetheless.

[phate4u]

That's just the reflection of the ball...

[Jayjs1989]

definitely photoshopped

[BradLA167]

no, I don't think it was photoshopped.

it was probably done in a 3d program like

3d studio max.

[itsajamesfest]

Really? Photoshop? Have you ever used Photoshop?

[Frekalishous]

DC66 that sounded really smart and i had no idea what all that meant. haha

[DCS66]

This video visualize the transformation of the kinetic energie into termal energie. Visualize also the mathematics of physics in our everyday molecular level. To compute this sequence in a equal resolution, i guess a state of the art supercomputer needs hours or days. In nature the same happens in realtime, without any calculation. Nature is like a realized, amazing dance of mathematics, rendered in "realtime". Finally matter is nothing u really can touch, it's "only" the effect of a process...

[savingsilverman]

Yeah...dido

[helllose]

it wouldnt take days to compute that , only a few minutes for a good computer

[SpamFairy]

some of what you said made sense, but this video has nothing to do with thermodynamics....

[allstarn08]

holy shit. My brain just melted

[knark32]

i love how people seem to be dislike your post, simply because they can't understand what you are saying-er, typing.

[ciucinciu]

i cant photoshop a movie idiot!!!

[Cheesymcnoodle]

well you can videoshop it, but i am fairly positive it hasn't been.

[scooterbooterscott]

I agree... totally photoshopped.. you can tell by the mistake at 0:17

[webbugt]

how can a video be photoshopped????

I hate you nerds who just say that, without even looking at the vid

[firefly300]

I think it's sand dillued with water, really wet sand...

[issaccheriyathu]

wet sand sticks together. I've done these kind of experiments.

Really fine, extremely dry sand acts like a fluid. This video looks legitimate with the observations that I've made at the Univ of Illinois.

[RareReality]

I'd say it was dry quicksand.

[WildAnimalJack]

Was that dropped or shot? Looked like a little too big of a reaction to be a drop (not to mention the seemingly quite rapid 'fall', despite being in time lapse).

[rudysmustache]

I think it's because the sand is really fine

[mikekearn]

Well, unless they filmed it in a vacuum, air resistance would slow down anything not able to deftly punch through it, like an iron ball, for example. The fine sand, on the other hand, would be very susceptible to being slowed by air resistance due to their diminutive size.

[DCS66]

hi mikekearn. I don't think it's filmed in a evacuated environment. See at 0:19 where the particles don't fall down with the same acceleration. In a vacuum, every matter accelerate with the same speed under equal gravitation conditions in direction to the local gravitation center. the Apollo 11 Crew executed this experiment on the surface of moon for brodcast on TV. From 0:19 you can see particles remains like dust. That's why i think it's filmed in a gas medium.

[webbugt]

nice explanation

[punkrocksknot]

thats pretty sick!!

[domenriono]

it looks like liquid sand.

[Sticktator]

ooooooooooooooooooooooooooo

[heymikedude1]

most awesome thing i've seen all week

[ALEXOVNI]

Lol, mustn't be too nice where you live? ;)

[Alwaysprime]

ya I didn't expect that shooting up column or the second dome explosion... I would like to see a break down of how the force created that reaction...

[Yaemes]

looks like very wet sand to me...

[KITabyssinian]

is the iron sand wet?

[JohnLennonFollower]

It looks like quicksand or something.

[DRopDRopG]

its cool

[DRopDRopG]

its coool:D

[DRopDRopG]

its coool
