If you're looking for an easy way to make an ordinary screwdriver seem magical, try this air-powered trick. Ben explains how it works with a simple air compressor, as well as the physics behind the trick. He even shows us how a screwdriver's structure and the dynamics of air flow can work together to make the screwdriver levitate in the air.
Bernoulli's principle
Using air pressure to spin a screwdriver can be a fun way to teach physics. This trick requires using a compressor and an air-powered screwdriver. You can learn more about the principle from Ben's video. The video describes the process, which includes airflow dynamics and the structure of a screwdriver.
Ping pong ball spins with air
Ping pong balls spin with air to produce a variety of effects. Topspin is achieved by giving the ball a sharp upward curve, and sidespin is achieved by giving it a sideways curve. Both of these spins cause the ball to bounce differently when it hits the table. Each spin requires a different technique to produce, and each will suit different situations. For the best results, you must have a basic understanding of how the ball moves and how to apply it.
Without spin, the ball travels through the air at the same speed as the air around it. This equalization creates pressure forces that balance the ball's path, while spin causes it to deviate from the intended path. As a result, the ball can travel higher or lower, and even go off the table. This makes the ball more difficult for your opponent to control and hit.
The spin of a ping pong ball can be imparted by brushing the ball with the racket. Usually, the racket is used at a 90 degree angle, but you can also use it sideways and upward. The faster you brush the ball, the faster it will spin. It will also travel a shorter distance.
A well-spun serve has a side-to-side curve that is easily visible in a birds eye view. As a ping pong player, you need to watch your opponent's technique and determine which of your strokes will make the ball spin more effectively.
