Surface Tension

In this activity exploring liquid dynamics, learners design and build a clay channel in a tray of water and then see what happens when food coloring and liquid soap are added to the mix. The activity also has suggestions on how to extend the experiment for older learners once they understand the basic concept of surface tension.
