In “salting out” demonstrations, a mixture of water and an organic liquid separates into two layers upon addition of an inorganic salt.^1-4 Typically, acetone or various alcohols are used for the organic liquid, while NaCl, Na₂CO₃, or K₂CO₃ are used as the salt.

Have you seen the rainbow candy experiment? It's a very simple experiment that involves pouring water into a plate that has M&M's candies or Skittles arranged in a pattern. Very curious shapes of sharply divided regions form spontaneously. How does this happen?! 

It's almost time for the Fouth of July here in the United States of America. In honor of my country, I'd like to share the following chemical mystery, which involves the colors red, white, and blue: just like the American flag! Check out the video below, and see if you can't solve the mystery of the colors appearing "out of the blue"!

In this post I’ll be sharing a bit about the chemistry of the Berry food color found in McCormick’s Color from Nature food coloring. I will also describe some experiments and demonstrations that can be done using this food color.
