Watch What Happens When M&M’s Dissolve Into Water
I'm not really sure why this is so cool, but it is. A photographer decided to find out what happens when M&M's dissolve into water and the result is pretty awesome.
This is a 4K time-lapse of several different colors of M&M's in water. The ACS Chemistry For Life website has a pretty good description of what's happening.
The candy coating is made up of coloring and sugar. The coloring and the sugar molecules both have positive and negative charges on them. The water molecule has positive and negative charges so it can attract and dissolve the color and sugar pretty well.
I have no idea what those chemists just said. All I know is that I spent a very unhealthy amount of time watching that video. So, there's that.
