This jumping colors science activity had our whole family – including my husband – watching in amazement. It was truly beautiful to watch the colors jump. But it also provided my kids with a basic introduction to the science of soap.

To do this jumping colors activity, I gathered the following materials:
- A bottle of half and half (any kind of milk product will do, but the higher the fat content the better the experiment works, which is why I chose to use half and half)
- Our Colorations Liquid Watercolor Paints
- Plastic pipettes
- A pie tin
- Dish washing soap
I started by pouring a shallow layer (about 1/4 inch) of half and half into the pie tin.
Once they had dripped in all the colors, I squirted a small pump of dishwashing soap in to the middle of the pie tin.
Amazement ensued as we watched the colors jump very quickly to the edge of the pie tin. Then we watched as they slowly began to come back to the center.
The kids loved it, and we still had more half and half. So I gave each of them their own tupperware with a layer of half and half to continue experimenting. It was so cool to watch the colors they dripped in jump to the side of the container and then slowly make their way back to the center.
