The World's Strongest Glue

missing_myself writes "Yahoo news reports the world's strongest glue is made by bacteria. "The adhesive can withstand an enormous amount of stress, equal to the force felt by a quarter with more than three cars piled on top of it." Time to get rid of the duct tape? "

Time to replace the adhesive on duct tape with this stuff!

Think twice about that suggestion the next time you accidentally (or on purpose) stick some duct tape to any part of your exposed flesh.

Or something close... it was alive and sticky, that's for sure.

How do we get it out of the bottle?

[kbob88 (951258)]

If it's that sticky, how do we ever get it out of the bottle?

On another note, this stuff would would really make the old glue-friend's-hand-to-forehead-or-other-body-part prank very painful...

Good point!

[Spy der Mann (805235)]

I recall (from my Dungeons n dragons times) that there was some kind of super-glue and some kind of super-oil. You needed the super-oil to apply it into the superglue bottle so it wouldn't stick.

Taking into account that the researchers are having problems with getting the glue off the instruments they use to fabricate it, perhaps we do need a super-oil in this case.

(And fact is stranger than fiction once more!)

An Idea I just came up with is that the superglue could be embedded inside small (nano? hmmm) part

Teflon too

[kbob88 (951258)]

Apparently something similar happened with Teflon too. The engineers at Dupont spent a very long time trying to get it to adhere to various surfaces. Teflon is so non-sticky that it took them years to get it to stick to metal pots and pans. Finally they came up with techniques of multiple layering and various methods to bake it on.

Re:Teflon too

[ScrewMaster (602015)]

Yes, and the bonding technique is fairly costly, I understand. I read about a new process a few years ago that used high voltage arcs to bond teflon to metal. Supposedly it was substantially cheaper but I don't know if they ever went anywhere with it.

And Murphy's law says.....

Amazing new unit

[qbwiz (87077)]

I'd never heard of this new "cars/quarter" unit (invented by the same guy who gave us the LoC unit, presumably), so I had to look it up [iu.edu] to see that this glue can hold around 10,000 psi (70,000 kPa).

Re:Amazing new unit

[marcosdumay (620877)]

70 MPa (~700 atm) is much better. Tank you.

It is even worse because people that are not from the United States (like me) don't even know what a quarter looks like. So, this 'intuitive' measurement is anthing but it.

Re:Amazing new unit

It's about twice the diameter of a dime.

[Firehed (942385)]

Not to mention that cars don't all weigh the same amount and not too many people have the vaguest idea of what three cars stacked vertically exhert on about a round inch (like a square inch, but not as pointy on the corners). I'm definately thinking something relative to a fat woman in stilettos puncturing your foot would be more world-friendly.

Of course, the unit makes almost no sense anyways, because most people are going to puzzle about the force it takes to tear two glued things apart when the measur

Re:Amazing new unit

[grimsweep (578372)]

That's easy. Just take any non-American car of a similar make and model. Then, find the ten most crucial parts of the engine that contribute to longer life. Replace them with the cheapest parts that you can find on the market, and add a ton or two to the frame to reduce gas milage.

Viola! Instant American-made vehicle.

Re:Amazing new unit

[Manchot (847225)]

Are you kidding me? Cars/quarter is definitely an SI unit, just like the area of a football field and the thickness of a human hair.

I'm sure Elmer will say they have a patent on sticking one thing to another. Or maybe that was the Porn Industry's patent.

You don't get it, do you? This is America. The land of the stupid measurements. Where there's 12 inches to a foot, 3 feet to a yard, 1760 yards to the mile, 16 ounces to a pound, 2000 pounds to the short ton and getting 543816 votes more than your opponent means you lose an election.

Sorry... couldn't help myself. God bless America for boobies and donuts! :)

Get rid of it?! No way! I say improve it. Imagine duct tape combined with this supersuperglue. My God, it'd be like Astroboy and Atlas working together to defeat a common foe!

Compression, tension, shear?

[corsec67 (627446)]

How strong is this glue under tension and shear?

I have an invisible glue here that can withstand an infinite amount of force under compression, and it is massless. Tension is a while 'nother matter.

Re:Compression, tension, shear?

[colinrichardday (768814)]

Compression is pushing in on something, like cars on the road (the cars compress the road). Tension is pulling out on something, like hanging a weight on a string (the weight applies tension to the string). Shear involves applying a sideway force, like using shears to cut paper. The shears cut through the paper, and the cut is along the paper.

Reinforced concrete combines the compression strength of concrete with the tensile strength of steel.

Glue Bacteria?

[suv4x4 (956391)]

"The single-celled bacterium uses sugar molecules to stay put in rivers, streams, and water pipes, a new study found."

Now... if I feed it something (like, I guess sugar), would it grow though? Imagine the instructions: "mix with sugar 4:1"...

And further, if I use it to glue a broken sugar bowl, should I expect a self-replicating glue disaster?

"It's not clear how the glue actually works, however, but researchers presume some special proteins must be attached to the sugars."

Well that sounds ensuring, right guys. Reminds me of that movie, The Stuff (1985) [imdb.com].

A bunch of scientists like our folks here, discover weird white substance on one of the Earth Poles (please save me the jokes on what you think it was). So naturally, what you think he does? He tastes it, and it's good.
So they just come with the tankers and start pumping it out and selling it as food. Turns out it eats you from the inside and turns you into a zombie.

By the way, has anyone tried to eat that glue and see what it tastes like?

Tell bad duct-tape joke; *duct*

[jolshefsky (560014)]

There's no way to get rid of duct tape. It has been so well marketed that people actually believe it is superior to other tapes. There's no force stronger than a belligerently held opinion.

I mean, the duct-tape has a gummy glue that dries out, the fibrous tape tears easily, has poor high-temperature properties, and is not waterproof. What more could you want?

Entropic end of Earth Imminent

[Vo0k (760020)]

Bacteria are known to mutate, right?
Some mutations spread uncontrollably, known fact.
Sugar is one of more common substances in the world.

Imagine the world where stepping on the grass means they have to amputate your legs to free you. And the glue infection spreading, things getting gradually more sticky everywhere. Up to the point when everyone is glued to the ground, and everything that moves, stops. Entropic death, no more movement.

I for one welcome our sticky bacterial overlords.

Would the force change if 3 cars were piled onto a surface that was 1 square meter - no....

Well, if there's more surface area, then there's a wider distribution of weight and the pressure per square inch would diminish.

Re:super super glue remover

[ScrewMaster (602015)]

I remember when Eastman 910 was sold at retail back in the mid-seventies. That stuff was incredible (it was eventually diluted and sold as Crazy Glue) all you had to do was got a tiny drop of it on your hands and touch something and the only way you'd get it off was to lose skin. I accidentally glued my left index finger to my forehead ... not funny. No, not funny at all. We eventually discovered that acetone would dissolve it but in the meantime I had my goddamn hand stuck to my head for several hours. A friend of my mothers' glued her hand to her nose. Now that was funny. And it happened instantly, you didn't get a chance to pull it loose.
