Product Details:
Packaging TypeBox
MaterialPlastic
Usage/ApplicationClassroom & Lab Experiment
Size25 cm (L) x 15 cm (W) x 10 cm (H)
ShapeRectangular Box
The Floating Ball Experiment demonstrates Bernoulli’s Principle, which explains how air pressure decreases as the speed of the air increases. In this experiment, a lightweight ball (such as a ping pong ball or foam ball) is placed above an air stream coming from a fan or blower inside a tube. When the device is turned on, the fan pushes air upward through the tube, creating a fast-moving column of air.
