Meet SLIPS , the most slippery material in the world. SLIPS stands for ‘Slippery Liquid-Infused Porous Surface’. Joanne Aizenberg, a scientist in Harvard invented it by adding a lubricating film inside a spongy layer of Teflon. The result is an ‘omniphobic’ surface – it repels both water and oil-based fluids.
Whats the most slippery substance on earth?
More slip- pery, it turned out, than ice in contact with ice. In fact, the low static coefficient of fric- tion of Teflon-on-Teflon , 0.04, made it the most slippery solid substance on earth.
Which is the most slippery oil?
Results. The results of slip risk from the AHP indicate that grease is the most slippery of the six contaminants, followed by diesel engine oil, hydraulic oil, cooking oil, water-soluble cutting oil, and water in a decreasing order of slipperiness.
What are some slippery substances?

- Spilled liquid; or.
- Floor polish or wax.
What is super slippery?
The ‘super slippery’ industrial packaging combines a cheap plastic with natural oils like cottonseed that is added to the interior surface – so sticky foods slide out with ease.
Which plastic is most slippery?
The resulting product is one that possesses the strength, toughness, and dimensional stability of Acetal with the added properties of PTFE , which is one of the world’s most slippery solid materials. In fact, PTFE, commonly known as Teflon®, is used as the non-stick material on cookware.
What is slippery oil?
General Information. Slippery Goo is multi-purpose, lithium-based, extreme pressure grease . Slippery Goo meets the demands of water and heat resistance needed in today’s farm equipment because it is enhanced with tackifiers and extreme pressure additives.
What makes oil more slippery?
Oil or grease: Oil molecules tend to have more friction with each other than with other objects around them (a property called viscosity). This dynamic causes oil molecules to move easily with almost anything that touches them; this is why oil on any surface makes the surface more slippery.
What is castor oil?
Castor oil is a multi-purpose vegetable oil that people have used for thousands of years. It’s made by extracting oil from the seeds of the Ricinus communis plant . These seeds, which are known as castor beans, contain a toxic enzyme called ricin. ... Castor oil has a number of medicinal, industrial and pharmaceutical uses.
What is BAM material?
The answer is BAM – a ceramic alloy created by combining a mix of boron, aluminum and magnesium with titanium diboride . The world’s third hardest material, next to diamond and cubic boron nitride, BAM is as slippery as it is strong.
What is more slippery than Teflon?
BAM – or boron-aluminum-magnesium alloy combined with titanium boride is super hard and slicker than Teflon. This “ceramic alloy” is the hardest material after diamond and cubic boron nitride.
How do you make plastic super slippery?
Rub wax paper over the entire plastic slide surface . It sounds too simple, but it actually works. When you rub the wax paper on the surface of your plastic slide, it transfers the food-safe wax making your slide slippery again.
What plant did Harvard engineers study to develop slips?
SLIPS technology, inspired by the Nepenthes pitcher plant , provides unique capabilities that are unmatched by any other liquid-repellent surface technologies. Credit: Wyss Institute at Harvard University.
How do you make a surface slicker?
It was magic . OK, fine. It was physics. And the physics of slippery surfaces could be far more revolutionary than a trick for saving a few ounces of condiment.
How do you make super slippery wood?
The most natural and common way of making wood slippery is by applying olive oil . Olive oil will get the job done and are quite environmentally friendly as well. However, if your slide is made out of unvarnished plywood, then the olive oil will get soaked up, and the roughness of the wood will persist.
What is the slipperiest metal?
The material, dubbed BAM , was accidentally discovered at the US Department of Energy Ames Laboratory in Iowa in 1999 following attempts to create a substance that generates electricity when heated.
Is Teflon stronger than UHMW?
UHMW has superior mechanical properties for wear, compressive strength, and impact resistance. Teflon is comparably soft and will creep due to its chemical structure.
Why is ice slippery?
It’s well understood that ice is slippery, just like water is wet. ... The friction on the ice causes a very thin layer of water to develop on top . That little bit of water laid over the icy surface is what causes the slipperiness. The thin layer of water reduces the friction of the surface, making it more slick.
Is Teflon a UHMW?
Differences Between UHMW and PTFE
UHMW (ultra high molecular weight polyethylene) is an extremely tough plastic with high abrasion and wear resistance. ... PTFE (polytetrefluoroethylene) is a soft, low friction fluoropolymer with outstanding chemical resistance and weathering resistance.
What is PTFE in lubricants?
PTFE stands for Polytetrafluoroethylene , which is a synthetic fluoropolymer. ... When used as a lubricant, PTFE can reduce friction, wear, and energy consumption of machinery. PTFE colloids, well known for their low friction, have at first glance, great appeal as oil additives.
Why is water a poor lubricant?
A “good” lubricant need to separate two surfaces that would normally be in contact, and the lubricant material must be able to move easily and be somewhat fluid to enable movement. Water is generally not very good at separating two surfaces that are in contact but it disperses too easily .
Why is crude oil a much better lubricant than water?
The higher the viscosity of the lubricant , the greater the pressure buildup and the greater the normal load that the bearing can support. That’s why we use lubricants with higher viscosity than water.
Is coconut oil for hair?
In addition to being good for your scalp, coconut oil also moisturizes your hair . Since it’s easily absorbed, it works better than other oils at repairing dry hair. Keep in mind that coconut oil alone may not be effective as a shampoo to cleanse hair, but as a pre-shampoo treatment, it will condition hair.
Which oil is best for hair?
- Coconut oil. Virgin coconut oil is the most commonly used hair oil, especially in South Asia. ...
- Sesame oil. Ideal for vata type hair, sesame oil reduces frizziness and may also prevent split ends. ...
- Almond oil. ...
- Argan oil. ...
- Moringa oil. ...
- Bhringraj or amla oil.
Can I drink castor oil?
Ingesting too much castor oil can cause nausea , cramps, dizziness, and muscle weakness. Use it as advised by your doctor and don’t take it on an empty stomach. Because castor oil may help induce labor, pregnant women should avoid it.
What is the lowest friction surface?
PTFE has the lowest coefficient of friction of any solid material.
Can a slip take place on a dry surface?
In order to prevent slips from happening on a dry surface, make sure that you are sweeping and dusting the floor on a regular basis . This will prevent any buildup of dust and other fine substances from settling on the floor.
What is liquid-infused surfaces?
Liquid-infused surfaces (LIS) are structured surfaces that are infused with a layer of a viscous liquid , which creates a smooth interface on which most immiscible liquids can flow without sticking or spreading.
What material is better than Teflon?
The most important thing is that ceramic is more non-stick than Teflon and you can cook things like eggs without needing oil. Ceramic is an excellent heat conductor, even when used on irons; the surface on the pan gets hot evenly.
What has the lowest friction coefficient?
Friction and the Fluorocarbons
PTFE has the lowest recorded m value for any material with a dynamic coefficient of friction of between 0.05 and 0.15 and a static coefficient of friction of approximately 0.05.
What substance has least friction?
PTFE has one of the lowest coefficients of friction of any solid.
Is PTFE slippery?
Teflon is the trademark name for PTFE, a type of plastic. ... You might not realize, as you fry your morning eggs, that PTFE is one of the most slippery materials that can be manufactured . It’s about as slippery as wet ice.
How do you make a metal slide slippery?
- Make a Cleaning Solution. Make a cleaning solution using warm water and a mild dish detergent. ...
- Scrub Down the Slide. You’ll want to use an abrasive rag or hand towel to scrub the slide from top to bottom. ...
- Let it Dry. ...
- Wax the Slide Itself. ...
- Sand the Slide Surface (If Needed)
Can you paint plastic slides?
Completely wash and dry the slide before painting. I used tsp and a rag to really scrub off any of the leftover dirt and debris. ... Paint the slide using even coats of spray paint , allowing it to completely dry between coats. I gave our slide three coats of spray paint for lasting durability.
