LiquiGlide, developed by a team at MIT's Varanasi Research Group, is a surface coating that liberates the notoriously non-Newtonian fluid ketchup from its glass- or plastic-walled prison. The research came in second in MIT's $100K Entrepreneurship Challenge, and is almost certainly destined for a bottle near you. Watch its graceful performance below in a video from Fast Co.Exist.

We have seen slippery materials before, but never in so useful an application. Creator Dave Smith tells Fast Co. that the heavily patented coating on the inside of the bottle is "kind of a structured liquid--it's rigid like a solid, but it's lubricated like a liquid."

Here it is with mayo:

I wonder what upper heat tolerance of this coating is? Perhaps it could be added in a blend with our lubricating oils in automotive engines, to enhance their ability to lubricate and cool the engine. And if not added to the oil, perhaps engine parts could be coated prior to being assembled?

The video of the ketchup and mayo is interesting, providing the coating is not hazardous to humans.

I wish POPSCI give more details of this coating.

How much does it cost to coat one bottle? Will the added bottle price exceed that pesky little bit of ketchup that's always left behind?

I like nonsense, it wakes up the brain cells.

Well i,m not even a little empressed, 30 years ago yeah way back when bottles were made of glassware. I haven,t seen a glass bottle in years until todays ketchup video. The mayo still had to be squeezed out. Its never been a problem getting the substance to the lip of the bottle but just getting it past the bottle neck and with plastics its an easy squeeze out. Brings to mind an old song. War! What is it good for? Absoultly nothing. So far as saftey for consumption its probally a plant based silica material and ok also meaning it would poop out in a piston wall in about a 1/3 of piston stroke and gum up the cylinder. But I do see one potential use for it if I worked in a superglue factory, I could just dip my hands in it and hand load the tubes and cut down on that ridiculously and costly man made machine labor. And don,t even think about coating a airplans wings with it. Ice magnet and flow reduction anyone.

I need to self correct. The ketchup bottle is plastic and the pourer of it made sure there was no upper contact with the lip, could not do that with the mayo and had to squeeze. Does popsi even watch these things I wonder.

I wonder if they could use a variation this coating on touch screen phones? If they could use it to keep fingerprints from sticking to the screen, that would be awesome!

can this be applied to peanut butter jars?

Looks promising, but I'll bet 10 years after american industry incorporates it into all of our food packaging, they find that it builds up in the body and causes some sort of nasty illness. The food industry will cover this fact up until enough fear builds up in the american physhe that people start to avoid it, impacting sales. Once that happens, the food industry will rename it and continue to use it until the law suits start. A couple of years after the first victim wins their lawsuit and all of the appeals have been exhausted (and that victim dies), then they will start to withdraw it from the market "for your safety". Keep it simple, use a butter knife to get what you can, then rinse the jar out and recycle it.

Don,t take me to harshly, I do love Popsi.

Don't get too excited. It probably causes cancer or something.

@mad_max,

i wouldnt be surprised.... all it does is add microscopic chemicals to the food. not worth paying double for...

This coating has incredible applications everywhere!

These could great for getting ketchup out of bottles or mayo out of jars, but once consume by humans, may cause a speed relief from constipation too.

Not all gifts are true gifts... ;)

I think that in addition to being non-Euclidean ketchup is also non-Newtonian. A brief search confirmed that All fluids are non-Euclidean, since Euclidean fluids do not seem to exist...

jimcool...awesome you love popsci, but really, you are surprised they have to squeeze the mayo out, not like it would pour out, if this is no more harmful than vegy oil than great, cheers

Do it with a full bottle of ketchup and I might feign being impressed.

... Yup, I'm calling Black Magic on this one.

"non-Euclidean fluid ketchup from its glass"

I think you were trying to say non-Newtonian. I noticed that people who write for Popular Science have a firm grasp of "POPULAR" and very little actual knowledge of "SCIENCE".

Thanks, guys. Knew I could count on you. I've been reading too many geometry texts this week.

@Paul Adams...it is funny how people on here think this is all you guys do, i bet you folks whip these up in a few minutes and then go on with the rest of your day, cheers

From the linked article "One of the most significant challenges his team faced was making sure the coating was food safe, meaning his team could only work with materials the FDA had approved." That doesn't mean that it has the FDA stamp on it yet but hopefully wouldn't be that hard to put on it. My questions are, will it stick to more than plastic and glass and what are the temperature limits?

You know, I was just reading the article in the latest PS mag about the nanoparticle coatings for say, iphones, last night. But to read this, with a FOOD GRADE coating like that makes me think, what about a human-based coating, say for bloodflow. If you could put a coating on the inside lining of your arteries, you might end up with much better bloodflower, easing blood pressure with no blockages or bottlenecks in arterial pressure. Without the ability of cholesterol or plaque to build up on the walls there, you would reduce the incidence of HBP and stroke, from bits of buildup breaking free and hitting another bottleneck....I want a finder's fee!

@ skarm

If it sticks to the walls of arteries there's a good chance it could stick in the smallest part of the circulatory system, as in the capillaries. The smallest nooks and crannies would be there and if you gunk things up in a way to inhibit the exchange of water, oxygen, carbon dioxide,etc., you'd be in big trouble,

let alone just clogging the vessels that are only one-millionth of a metre (or one-thousandth of a millimetre, 0.001 mm, or about 0.000039 inches) thick, things might just clog, up.
I dunno,but painting the inside of your arteries with some slick 50 type of even a form of veggie oil, does not seem too promising from my view. Just a thought.

your right, some vessels only let one blood cell through at a time, cheers

With a full bottle of ketchup, get some air into the bottle first by tapping the bottle on your hand on one side, the air pocket then allows the sauce to pour out

I'm still not sold on the idea of using it in food applications. But there are many other uses for this coating that come to my mind. Such as...

Car windshield
Car paint
Home paint
Appliance paint
Home and skyscraper windows.
Inside of sink drains. (no more clogs)
Reading glasses

Not to mention thousands of industrial applications.

SH#T! Now I did it! I dump the whole ketchup on my burger. What a mess, sheesh!

I thought we all moved on to salsa?
