Experiment: Soap and Black Pepper the Materials we need:1. Small amount of black pepper.2. Liquid soap. 3 Water . 4 Small container Steps: 1. Prepare a small container and fill it with water. 2. Carefully sprinkle the black pepper onto the surface of the water . Observe how the pepper gathers on the surface of the water due to surface tension. 3. Now put liquid soap on your finger and try to place it in the middle of the bowl. You will see that the pepper moves away from the middle This experiment demonstrates how soap affects surface tension forces, leading to the dispersion of particles such as black pepper on the surface of the water.

Materials used in the experiment of making a ferromagnetic fluid:

Pour a bit of vegetable oil into a shallow dish, just enough to make a thin film across the bottom. Pour iron filings into the oil and mix the two until they have become a thick, sludge-like material. This is your ferrofluid! Use a napkin to absorb any excess oil and allow the ferrofluid to become thicker.
