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,

I suspect that the food color gel has a base that is heavier than water. Experiments are cool.

Veryyy interesting!

I agree. It would be interesting to compare gel and liquid food coloring in a layer experiment!

I thought so too. I had no idea it would be more dense.
