Surprise others with this great trick!

This is a fun science trick that you can show your family and friends. All you need is

some water, a bowl, some pepper, and some liquid soap (the type used to wash dishes).

Here is what to do:

1. Put some water in the bowl.

2. Put some pepper in the bowl. The pepper will float on top of the water. It

does not fall to the bottom of the bowl. Use enough pepper to cover the

water.

3. Place the tip of your finger in the water. Nothing happens.

4. Now, put a bit of liquid soap on your finger.

5. Place the tip of your finger in the water again. This time, the pepper should

move quickly to the sides of the bowl. It looks like the pepper is afraid of the

soap!

Try again!

What happens if you try using other materials, such as milk or lemon juice? Find out!

Start with a new bowl, and put some water and pepper in it, just like you did before.

Now, put some lemon juice on your finger. When you place your finger in the water, the

pepper should not move. Try again with milk. The pepper should stay where it is again.

The trick only works with soap!
