Carbon dioxide experiment device










Image Number 3 for United States Patent #7637742.

A carbon dioxide gas buoyancy experiment device that can demonstrate how the buoyancy force acts against the force of gravity and how an object's buoyancy in a fluid can be manipulated by altering the object's density. The device demonstrates how the buoyancy force works in practice by submerging bundles of hydrophobic fingers capable of collecting gas into a gas releasing liquid such as soda. As the finger bundles collect gas bubbles released by the liquid, the volume of the submerged finger bundles increases, thereby increasing their buoyancy and causing the finger bundles to ascend and float in the liquid. The finger bundles can be pushed back down in the liquid, but will rise again due to the increased buoyancy imparted by the gas bubbles that adhere to the finger bundles.
