In the video, a man is standing on a stage holding two sticks. He is wearing a green shirt and blue pants. The stage has a large red sign with the letters "TEDx" on it. The man is using the sticks to hit a green ball that is attached to a string. The ball is being pulled up and down by the sticks. The man is also wearing a green hat and has a microphone attached to his shirt. The background of the stage is dark, and there are chairs and a table visible. The man appears to be performing a magic trick or a science experiment.
