Explanation
|
|
| The ball floats above the hair dryer as the airflow from the hair dryer pushes the ball upwards. The air flow from the dryer, make the pressure lower where as the air pressure on the other side of the ball is greater. So the outer pressure makes the ball lie inside the coloumn. The same experiment can be done with 2 - 3 balls. |
