It's easy to demonstrate the action of an emulsifer. All you need are two immiscible liquids and a little dishwashing detergent or soap.
Emulsifier Demo Materials
- kerosene or oil
- dishwashing detergent or soap
- flask or clear glass
Perform the Demonstration
- Add some kerosene or oil together with some water in a flask. Swirl the contents around to try to mix them. What happens?
