• A bowl
• Liquid dish soap or shampoo
• An old refill pen
• Glycerin


1. In a bowl, add two tablespoons of dish soap and one tablespoon of glycerin.

2. Add some water (Be careful not to add to much) and mix the solution thoroughly.

3. Take an old refill pen and unscrew both ends. Discard the refill and use the body of the pen as a bubble wand.

4. Dip one end of the bubble wand into the solution and blow gently through the other end.

See: You will see bubbles forming on the other end of the bubble wand.

Think about:
Why does adding soap to water form bubbles?
Surface tension is what keeps the molecules of a liquid together at the surface. While the surface tension of water is very strong, soap weakens it and allows the surface of the water to be stretched, helping form bubbles.

Let’s find out:
Why do bubbles pop?
Bubbles are very delicate as the water molecules at the surface are stretched very think. Anything that breaks up the layer of water molecules, releases the air and bursts the bubbles. The glycerin acts as a protective coating.
