When two fluids don't mix well, they sometimes form strange patterns called "viscous fingering," or Saffman-Taylor instability. Studying these patterns can help scientists understand how to design ...

Certain liquids do not want to play together: for an easy example, oil and water. If you put these two classic liquids together and try to mix them, the less dense oil will float on top.

Two polymer-containing liquids are then printed onto the surface – one contains clay and the other polymers. Within milliseconds, a thin channel of ~1mm in diameter is formed at the interface.

An evaporating droplet that contains two fluids can sprout fingerlike protrusions or a chain of smaller droplets around its edge, depending on the liquids in the mixture, researchers report ...

This is because food coloring is a polar liquid but oil is nonpolar. If you mix the two, you will see lots of little food-coloring drops dispersed in the oil, but both liquids do not mix.
