This is a very low-cost demonstration of Static Electricity. You will need two straws, a ball pen refill, eraser, a pin and some wool. Stand an old ball pen refill on a rubber eraser. Push a paper pin in the middle of a white straw. Place the pin in the refill so that the straw can rotate smoothly. Then rub both ends of the straw with wool. This will impart an Electrical Charge on the straw. Similarly rub the yellow straw and charge it electrically. Now the yellow straw will act like a magic wand! As you bring it close to the white straw it will be repelled. Without touching the straws the white straw can be made to obey the commands of the yellow straw. Here you can see children playing with this magic wand! This is a very low-cost and simple experiment.
