A very common experiment this is, But definitely not as lame as the other one...
Now put your finger dipped in soap (or you can just add soap)
YOU WILL REQUIRE:
A bowl full of water (choose one with a larger surface area)
2. Black Pepper
3. Soap
2. Black Pepper
3. Soap
STEP 1: Add pepper to the bowl full of water.
STEP 2: Put your finger in....Nothing happens
Now put your finger dipped in soap (or you can just add soap)
SEE THE MAGIC!
Well of course it isn't magic it;s SCIENCE!
It's not that the soap repels the pepper , but rather soap that readily breaks the high surface tension of water.The soap causes a break in surface tension making the surrounding water molecules to move away.
