The Floating S experiment, as it is called at the PreKinders website, is super easy to do and hardly any cost at all. The only materials you need is three different color Skittles placed S face up in a white disposable bowl (found in picnic area of supermarket) and a class of water. Place the skittles around the edge with some space between the three (think like a triangle). Pour enough water to cover the Skittles. Then observe. It is important to have the experiment take place where it is not shaky. The website has a printable to record observations too.
Some cool observations:
- The colors bled in an outer ring. When the colors met each other I thought they would start to mix (the red would meet the yellow and start to form orange). This didn't happen! The colors stopped when they met and decided to travel inwards.
- The red color traveled the fastest, then the green, and the yellow was the slowest.
- The white S floated to the top. You have to observe it quick because the S starts to break down to white floating stringy stuff.
