Water and oil don't mix, do they? We'll show you here how you can mix water and oil for a short time. You'll also see that this water and oil mixture, also called an "emulsion," is white, just like milk. Is there a connection?
Water and oil don’t mix, do they?
You will need
- Approx. 20 mL water
- Approx. 5 mL oil
- A clean spray bottle (approx. 500 mL capacity)
Let’s get started
1.Fill the spray bottle
Take the spray bottle and fill the bottle with water and oil one after the other. Close the bottle carefully and shake it briefly.
2. Spray mist
Now spray the mixture in the spray bottle into another water glass. A white, somewhat foamy mixture is formed in the water glass. This is known as an emulsion. Over time, the emulsion changes and the water and oil separate again. The emulsion was unstable.
Milk is also an emulsion. It is also white. Because milk has other ingredients besides oil and water that stabilize the emulsion, the milk remains white and does not separate.
