Layered Liquids and Unexpected Results

We tried an experiment with layers of liquids.

We filled a glass mostly with water

and added about 1/4 cup oil.

The oil floats.

We added a couple of drops

of food coloring gel.

Interestingly, the oil formed a type of bubble

around the food coloring as the dye

pushed its way through the oil.

Eventually, the oil separated and rose to the surface.

Then the dye started mixing with the water.

We let our project sit overnight.

The gel only mixed with part of the water,

then there was the clear level of water,

and on top there was the oil.

It's interesting that the colored water is more

dense and that it didn't mix with all of the water.

I wonder if that's because of the oil bubbles that formed

or because we used food color gel?

Did I mention that I learn something new everyday?

Wishing you homeschool blessings,
