You only need a few common kitchen ingredients to perform this science magic trick.
Plate or bowl
How to do:
- Pour water into a plate or bowl.
- Shake some pepper onto the water.

How the Pepper & Water Trick Works? Why does pepper spread in water when soap is added?
As the soap moves into the water and the surface tension changes, the pepper no longer floats on top. But the water molecules still want to keep the surface tension going, so they pull back away from the soap and carry the pepper along with them.
