Time for more fun with food coloring. We had previously used two colors to see whether salt water was slower to diffuse than fresh water. This time we repeated the experiment with two containers of differently colored fresh water. To our surprise, although the colors eventually seemed to meet in the middle, the red took days longer than the yellow color. It seems that whatever makes the different colors causes them to diffuse at different rates. We'll have to play around with that some more.
