The Ouzo Effect under the magnifying glass

The Ouzo Effect under the magnifying glass: Pour some water into your glass of ouzo or pastis, and the beverage will change from transparent to milky: this is the well-known 'Ouzo effect'. But what will happen if you simply place a drop of ouzo on a surface and wait? Scientists have studied the phenomena taking place, and distinguish four 'life phases' of the drop, within no more than a quarter of an hour.

Inverted Cereal Effect


How your breakfast cereal has some physics in it....a combination of surface tension, gravity and good cereal like Cheerios (better than Fruit Loops)

Read about it on New York Times:

Wired Article Link- The Beauty of the Laplace Equation- Mathematical Key to .... Everything


Kibron devices like the AquaPi and DeltaPi can measure the air-water interface of surface tension in films that are governed by  governed by Laplace's law of capillary action.  Read more about this brilliant equation in Wired.  Washing dishes will never be the same...

New surface makes oil contamination remove itself

New surface makes oil contamination remove itself: Researchers have developed surfaces where oil transports itself to desired directions. Researchers' oleophobic surfaces are microtextured with radial arrays of undercut stripes. When oil drops fall on surfaces, drops move away from the landing point to the direction set by asymmetric geometrical patterning of the surface. The surfaces open up new avenues for power-free liquid transportation and oil contamination self-removal applications in analytical and fluidic devices.

I wonder if  Kibron devices may be able aid in this research...

Water Molecules Break Bonds Through Quantum Tunneling

http://www.sciencemag.org/news/2016/03/water-molecules-break-bonds-through-quantum-tunneling




Water molecules rotate like gears to break bonds.....


See the video below.









Water forms all the bonds of life.   If there is a way that there is some order then it is interesting to understand how that affects the molcules that they are bound to.

Blood drying







If someone gets shot the blood droplets will hit the ground.  With enough time the Water from the blood will evaporate changing the surface tension gradient across the the droplet.  These gradients can cause convection inside the drop and pushes the red blood cells towards the outer part of the drop leaving different patterns.  The patterns depend on what parts of the blood are deposited. 


Looking at the patterns it can show a difference between different types of red blood cells e.g. anemic vs. normal blood.
