Experiment 8: (cont.)
We had some really interesting movement when we
added a drop of blue and red food coloring and then let
a couple drops of soap drip into the milk.
The kids really, really enjoyed this experiment! I highly
recommend this one.
I’ve seen this experiment in a number of places, but there’s
a good explanation of the science behind it all at:
