The Gravity Ball is a unique product from Science Park that allows you to defy gravity. It is a large spherical ball that is filled with a special fluid and contains a powerful magnet. When the ball is placed in a container, the fluid inside the ball reacts with the magnetic field and causes the ball to float. This floating sensation gives the user the feeling of gravity being defied as the ball appears to defy the laws of physics. The ball is perfect for a variety of activities and can be used for both educational and recreational purposes. Additionally, the Gravity Ball can be used as a unique way to learn about science, as it allows users to explore the principles of magnetism, density, and buoyancy.
