What's going on here? The two liquid soaps have different densities and do not mix. The lower density soap sits at the top and the higher density soap sinks to the bottom. Cool! This is very similar to the standard oil and water experiments in which the oil and water clearly separate due to different densities. The was another good opportunity to show off science to our daughters and offer an explanation.
The moral here is that science surrounds us. You just have to look for it!
