This is a fun quick activity you can do with your kids while you’re making dinner.
You’ll need a bowl, plate, or pie pan, pepper, water, and dish soap.
Fill your chosen container with water and sprinkle on some pepper.
Put your finger in the pepper/water and see what happens.
Not a whole lot! Now put a small bit of dish soap on your finger
Now put your finger in the pepper/water
and watch the amazement on your kids’ face. It happens really fast and is so fun so be prepared to reapeat this over and over.
If your kids are old enough you can talk to them about what is happening. To answer the original question, no, pepper is not afraid of water. When you think about a drop of rain you think of a bulging shape. The bulge is created by surface tension. Because the pepper is so light it just floats on top of the water. When the dish soap is introduced, the surface tension is lowered basically causing the bulging of the water to lower (or flatten) carrying the floating pepper to the outside.
