Materials Required:
- Large bowl
- Water
- Dishwashing liquid
- Scissors
- Paper cup
- Spoon
Procedure:
- Fill up the bowl with about one and a quarter litre of water; then add 4-5 tablespoonfuls of dishwashing liquid. Stir the water slowly, but do not beat it.
- Cut a ½ inch hole in the bottom of a paper cup. Now, dip the rim of the cup (the edge from which you normally drink) into the soapy water. Lift it slowly and blow through the small hole. A giant bubble will float into the air. Try to fill the air with several bubbles.
This is what happens:
The soap helps the water cling across the rim of the cup. When you blow, it acts like a thin skin around the bubble of air, the bubbles you are making are really puffs of air surrounded by water!
