Humans can hear the difference between hot and cold water being poured. This is because the viscosity of water will go down as temperature increases. npr.org/2014/07/05/328842…
In 1958 nuclear weapons were proposed as a tool for petroleum extraction. The plan was to detonate 100 nuclear bombs in the Alberta Oil Sands, thus adding heat and decreasing viscosity, the bitumen could then be easily pumped out. The project was put on hiatus due to risk of Soviet espionage. en.wikipedia.org/wiki/Pro…
When you cool helium to about 2 Kelvin it has literally zero viscosity and so can flow through solid ceramics and up walls. youtube.com/watch?v=2Z6UJ…
Viscosity removes the velocity difference between car and air close to the car, hence you can't clean the dust off your car by driving faster. revisionscience.com/a2-le…
Helium, when cooled to a superfluid, has zero viscosity. It can flow upwards, and create infinite frictionless fountains. youtube.com/watch?v=2Z6UJ…
The World's Longest Continuously Running Experiment began in 1927 at the University of Queensland Brisbane testing the viscosity of pitch - 8 drops have formed since it began. bbc.com/news/science-envi…
Select foods that contain natural dietary fiber, especially the water-soluble forms of dietary fiber in legumes, vegetables, and fruits. Soluble fiber tends to increase the viscosity or thickness of the intestinal contents after a meal, which slows carbohydrate digestion and glucose absorption. healthyeating.sfgate.com/…
The difference between ballpoint and rollerball pens isn't the pen, but the ink inside. Ballpoint pens use a paste-like oil-based ink while Rollerballs use low-viscosity water-based inks and gels to achieve an effect similar to a fountain pen. en.wikipedia.org/wiki/Rol…
The viscosity of Ketchup changes under stress, which is the reason why hitting and shaking the bottle makes it flow smoothly. Other examples of these so called "Non-Newtonian Fluids" are Flubber (slime) and plant resin. comsol.de/blogs/non-newto…
The world's longest-running laboratory experiment "demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats." In 1930 pitch was left in a glass funnel to drip out and has only dropped 9 times: about once every 10 years. smp.uq.edu.au/content/pit…
Liquid helium has zero viscosity and can flow through microscopic holes and up walls against gravity youtube.com/watch?v=2Z6UJ…
Data from the Critical Viscosity of Xenon-2 Experiment on the Fatal Columbia Space Shuttle Disaster Was thought to be Destroyed, but the Hard Drive was Recovered and 99% of the Data was Saved foxnews.com/story/2008/05…
When melting glass in space, zero gravity increases the viscosity and you can create glass with chemicals other than silica!! [x-post from r/glassblowing] science.nasa.gov/science-…
If Helium is cold enough, it will form a "superfluid" where it acts like a liquid with zero viscosity, meaning it will actually try to "climb" out of containers against gravity to escape. en.wikipedia.org/wiki/Sup…
The longest continuous experiment was started in 1927. The goal was to demonstrate that some substances that appear to be solid are in fact very-high-viscosity fluids. The viscosity of the pitch used is 230 billion times that of water, taking several years to form a single drop. en.wikipedia.org/wiki/Pit…
Ketchup is an example of a non-Newtonian liquid meaning it's viscosity is not constant. This explains why it is hard to get out of the bottle on the first try, it thins the more is it messed with. rsc.org/chemistryworld/Ne…
There was an experiment started in 1930(85 yrs ago) that still continues today about dripping pitch(tar) and recording its viscosity. Its so slow that its 9th drop happened only last year. newscientist.com/article/…
Pitch has a viscosity 230 billion times that of water. There is an experiment at U of Queensland; pitch was allowed to drip in 1930, and since that time only 8 drops have fallen. The last drop fell on 28/11/00, and the next drop is expected to fall this year. en.wikipedia.org/wiki/Pit…
The diesel engine was also designed to run off of vegetable oil, all it takes is lowering its viscosity en.wikipedia.org/wiki/Veg…
Pitch has a viscosity approximately 230 billion times that of water, and that petroleum-derived pitch (which is black) is the origin of the term 'pitch-black'. Oh, and the pitch drop experiment is the longest continuously running lab experiment - only 9 drips have dropped in over 84 years. en.wikipedia.org/wiki/Pit…
Due to its viscosity, cold water rinses away soap bubbles better when washing dishes. physicsforums.com/showthr…
Today I learned of the Mayonnaise effect - Structuring caused by the mixing of liquids or the addition of solutes to a solvent causes the viscosity to increase ncbi.nlm.nih.gov/pubmed/2…
Heinz ketchup exits the iconic glass bottle at .028 miles per hour. If the viscosity of the ketchup is greater than this speed, the ketchup is rejected for sale. heinz.com/our-company/pre…
An experiment to calculate the viscosity of Bitumen has been running since 1927, in which time only 9 drops have been recorded. en.m.wikipedia.org/wiki/P…
In 1958 there was a proposal to detonate up to 100 nuclear bombs underground the Alberta Oil Sands; β€œhypothetically, the heat and pressure would boil the bitumen deposits, reducing their viscosity to the point that standard oilfield techniques could be used.” en.wikipedia.org/wiki/Pro…
Liquid Helium becomes a "Superfluid" at 2Β° Kelvin giving it special properties such as no viscosity. [1:44] youtube.com/watch?v=2Z6UJ…
The longest-running scientific experiment was begun in 1927 and continues to this day. Its purpose is to measure the viscosity of pitch. 8 drops have fallen so far, which tells us that the viscosity is approx. 230 billion times that of water. smp.uq.edu.au/content/pit…
- An experiment has been running since 1927 with a liquid that has 230 billion times the viscosity of water en.wikipedia.org/wiki/Pit…
The word 'viscosity' is derived from the Latin word for mistletoe, 'viscum'. A viscous glue was made from mistletoe berries, used in trapping birds. en.wikipedia.org/wiki/Vis…
The viscosity of the common food emulsifier xanthan gum temporarily decreases when it is shaken, allowing you to mix salad dressings and blend drinks, but then thicken again once it is no longer agitated. en.wikipedia.org/wiki/Xan…
There is a state of matter that acts like a liquid but has no viscosity and can slow the speed of light to 17 m/s. en.wikipedia.org/wiki/Sup…
