A Bowl
• A Dash of Pepper

| Steps |
| |
1.
Fill the bowl with water.
2. Sprinkle
a dash of pepper in the bowl of water.
3. Add a drop
of liquid dish soap.
The pepper scurries away from
the soap.
This
is because the soap breaks the surface
tension of the water and the tension
on the rest of the water pulls the
floating pepper away from the soap. |
