Atomic trampoline

What a performance. Wow.

video source

The atomic trampoline coating is an amorphous metal alloy

That movie was called "Flubber" right?

All of his videos are about cool little toys, well worth watching.

So performance.

My favorite video with this guy

Much atomic

That guy is awesome.

You just know this guy has a British accent

When I'm on mobile I skip 100% of posted videos. On either mobile or desktop, I'll always view a gif, and if I'm interested, I'll read the comments to find (and upvote) the source.

It shouldn't since that would be released energy.

Very trampoline.

That movie was actually based on this finding when in nineteen ninety eight....

Investors: Is this coating well known?

Scientist: No, as I said, its a fairly recent discovery.

Investors: Great! Color it blue and say its made of moon dust in the marketing. I know at least one rich nut who's looking for something like this.

Here's an interesting little toy called the Fleshlight. Developed by NASA scientists fairly recently... around 1993, for astronaughts who spend lengthy times up there, all alone, orbiting our big blue planet with little contact with their loved ones. Here's how it works. zip CLOSE TAB

He was about to make a reference to when The Undertaker threw Mankind off the 16 foot hell in a cell back in 1998. I think it's a meme on reddit.


Tim is the most British man alive today. Fact.

Shakespearean actors playing King Henry are still only half as British as Tim when he talks about how remarkable his toy collection is.

(Bass drops about a minute in)

So if there was a magical surface that was perfectly bouncy, would it make any sound?

24 years ago. So practically yesterday.

I bet you he fucks.

Great video and great prank. My guess is, as it often is, some whole you have to cover with your finger?

Yeah, nah.

Link to his channel. It's his living.

It has been used in golf clubs but in fact it's been banned in competitions because of the obvious advantage it provides. One potential use for this material is in the biomedical industry, as these metals (also known as bulk metallic glasses, aka BMGs) are pretty much superior in every mechanical aspect to their normal crystalline counterparts!

Source: Did my Masters thesis on BMGs

Not really silly at all, the only particularly important property is the high coefficient of restitution, it hits things far. Golf clubs are about the only thing its useful for.

Then you've found yourself a brand new universe, bigger discovery than perpetual motion I'd imagine.

Just wondering, but why did OP choosed the GIF format rather than linking to the original video directly on youtube ?

I understand that a (silent/subtitled) GIF can be nice to some users but on the other hand it would be great to support the channel by giving them many much appreciated views.

Anyway, thanks for actually directing people to the original content creator !

and i find his voice soothing

Some of this on a bat would make baseball more exciting.

Course the ball would also vaporize a fans head on yeah, more exciting.

I'll watch any gif. I'll skip every video. I'm not alone on this sentiment.

The issue with me is that a YouTube video has to switch apps, make a connection, load, go full screen, buffer, potentially load an advert, then play. Only for me to have to switch back to RiF afterwards. It's incredibly annoying

The original came out way earlier.

Repulsion Pudding!

Repulsion Gel, I'm assuming?

This one is my favourite

I'd say the best lighter here is Tim himself because he lights up my life.

I found the channel on /sub/unintentional_asmr - began watching it because of his voice, and the general calmness of the show. Lots of nap time relaxing videos there.

The story behind that is awesome. The undertaker was trying to get man kind to quit, but he kept telling him no. No one planned when he fell through the cage onto the thumb tacks either. Mick Foley is just nuts.

After he went off the side of the cage, bounced off the table, and smacked into the railing one of his teeth ripped through his lip and was lodged in his nose.

I remember watching is live on PPV. Shit was nuts.

Just to be clear, the ball isn't actually moving faster, it just appears that way because the distance between it and the base is shrinking, right? He's a sciencey guy with glasses, so he's making me doubt myself.

Unfortunately Apple inc. has an exclusive use license​ for consumer electronics. So far they managed to make a sim card ejector...


Cmon bro just watch it

If 100% of the energy goes back into the ball then, nope, not possible.

If I remember right these metals are kind of like glass in that the atoms don't fit together properly because of their sizes, so they stay "liquid" instead of forming a proper crystalline structure. The most commercial use they saw was in golf clubs, I think, kinda silly really. it in a forest with no one around?


Just wondering, but why did OP choosed the GIF format rather than linking to the original video directly on youtube ?

Because gifs always get more upvotes than videos, it doesn't matter how long the gif is.

A small amount of the momentum would be converted to heat. So it would eventually stop bouncing.

I'd guess drag from air would slow it down

In physics, yes.

What if you put an atomic trampoline at the top of the tube? Will it bounce forever?

We haven't nailed down entirely what element it is yet, but its a lively one, and it does not like the human skeleton

"What fun"

Amorphous metals are nothing new. They are also called "glassy metals," because glass has an amorphous structure. The face of golf clubs often use a glassy metal because of better energy transfer from swing to ball.

Furthermore, almost any alloy can be made with an amorphous crystal lattice structure. To do this, you need to cool the metal from liquid phase extremely fast. The necessary rate of cooling required is inversely related to the amount of alloyed components. In plain english, this means alloys with 4, 5, 6 elements only need a slow cooling rate to achieve an amorphous, glassy structure. A metal with 1, 2 or 3 elements needs a very fast cooling rate to form a glassy structure.

FYI, "glassy" is synonymous with "amorphous." They are used interchangeably.

You can actually read the necessary speed of cooling for any alloy from a TTT diagram. Check this reddit post for why and how the thermodynamics work

They're brittle and unsharpenable. Suitable for neither the body nor the edge.

They might be interesting as a speaker element. Apple has the exclusive rights to LiquidMetal in the use of commercial consumer electronics for the foreseeable future; they had a run of sim eject tools made from the material for the iPhone 3G.

I want this guy as a grandpa for my son. He has already a great grandpa but if this men would be available for grandpa adoption I would take him.

There's two holes, one on the end that blows flour in your face, and another on the bottom that turns the wheel. Just cover the one on the end with your tongue to not be covered in flour.

Disclaimer, I didn't look at the video, but I'm pretty sure I know which one it is

For many of us.

Just started this part last night lol

Yes it would. The ball would still make an abrupt motion so it would create pressure waves aka sound. The magical surface wouldn't though. E:grammar

Yes, if it was patented that year, then it expired in 2013, but its likely that it went through a year or two later, so maybe it is freshly out of patent.

Or they never patented the process, and instead went the route of WD-40.

What if it was in a frictionless vacuum?

I was holding it together until that little puff of white smoke and then I lost it.

Liquidmetal is the brand name it's solid metal with properties of glass and plastic.


If the ingredients are a trade secret...

..there are ways to figure out the exact composition. And we already pretty much know the formula of WD-40, and companies make their own proprietary knock offs.

The only way to keep it a secret is if there was a special heat treatment or something to get it to work.

My thinking what

On tomorrow's news headline: "SCIENTIST SHOWS SPACE JUMP DEVICE"

It also doubles as a thermos

yeah bro cmon

Suck vs blow was my guess... If there was a hole I think Tim would've had to cover it

The point was that I've already seen it too many times and didn't need to open the link to know what they were talking about.

Yeah but what if it was in a frictionless vacuum and in an environment where the small amount of the momentum would not be converted to heat?

Or perhaps putting it in golf clubs and advertising it as a performance enhancer would be the most immediately profitable thing.

You should, just 1 min

In metallurgy the heating and cooling to precise temperatures has a huge influence.

Nothing very exciting happens.

Known to cause some serious cancer.

Yeah, I supposed the fact that GIFs are silent and easier to load on a mobile is handy for some. I'm just not sure when the length of the video is a bit longer like this one.

I will watch short GIFs on mobile during the day and sometimes look at longer videos using later on. For instance, I think this video is a bit cooler with the voice of this guy presenting the toy plus I can subscribe or add it to my watch later playlist when I like the content.

But I get the idea, GIFs are handy.

Wikipedia says that these alloys are highly wear resistant. Would they be useful in knife manufacture? The key characteristics we look for are hardness of around 60 Rockwell, resistance to the edge folding over and resistance to the edge being abraded. Plus corrosion resistance.

The knife industry frequently makes use of particle metallurgy steels and from reading WP it sounds as though BMGs are basically a souped-up version of that.

I'm sad that an anvil can get better FPS than my PC.

They couldn't find anyway to use this in an engine or used in conjunction with magnets to replace springs, or even hammers or something, anything. nope, golf

1993 - it should be off patent by now, I would think.

He's doing the u/shittymorph bit E:a word

Parent comment is alluding to the fact that a non entropic environment is not possible in our universe and therefore the hypothetical you proposed could only happen in a new, different universe.

Which, would be more interesting than perpetual motion.

Yeah, too brittle for a hardened face on an anvil. The heat might affect the phase of the alloy mixture as well.

Anvils with standard hardened faces, the faces are already so brittle that striking them with a tool can cause shards to splnter off and squirt out sideays at hundreds of FPS, and what's almost always right horizontally level with the anvil face? That's right: the suppurating-gut-wound abdomen, the family jewels, and the femoral "They drain themselves in seconds!" artery.


If you had a material that created 100% kinetic transfer you would be able to eliminate loss of power in transmission. That would solve a large chunk of the energy crises.

They actually do use this on big bertha drivers I've been told. You're not allowed to use them on tour.

No it doesn't. ASMR is a very different thing than frisson.

correct, it has a shorter distance to travel to each cycle has a shorter duration, i.e. the frequency increases as the amplitude decreases.

One of the best parts of the game for me!

That's his yayo machine

I'm sure if there was an obviously beneficial use for it in those ways, they would've focused on that instead of golf clubs.


Chances are something is in the works, but a product more complicated than a golf club is going to take some time.

Mobile users don't like video. GIFs get upvotes.

A bit of pedantry, but in an atmosphere, it'd be impossible to make a perfectly bouncy platform unless it contributed energy to the collision, since air resistance would take energy away. So a ball bouncing off a perfectly bouncy surface in an atmosphere does not exist because that's an impossible situation (unless the surface inputs energy, which is possible but I guess isn't what he was asking). The way I see it, the answer is either no (in a vacuum), or there is no answer (in an atmosphere). If we're assuming the surface put in energy, then you're definitely right.

Thanks for the link. I'm actually really jealous you got to see all that when it happened, it must have been insane. I remember Foley saying when he got to the back Vince thanked him but told him never to do that again.

What are you talking about? Some random dude on reddit should know better than all these so called "scientists". Especially after beeing educated by an in depth gif like this.
