Cartesian Diver, 100 mm Glass Archimedes Principle Demonstrator
$6.00(Ex GST)
• 100 mm glass Cartesian diver, classic buoyancy experiment for Archimedes principle demonstrations.
• Shows sink and rise behaviour as pressure changes, links density change to buoyant force effects.
• Demonstrates ideal gas law concept, pressure change affects trapped gas volume inside diver.
• Suitable for fluids lessons on pressure, density, and buoyancy in water-filled container setups.
• Simple classroom demonstrator, supports repeat trials and clear observation of buoyancy response.
- Description
Description
This 100 mm glass Cartesian diver is a classic buoyancy demonstrator used in basic physics and science practicals. When used in a water-filled container, the diver’s buoyancy changes as pressure on the surrounding water changes, providing a clear demonstration of Archimedes’ principle and gas behaviour.
The activity also links to the ideal gas law because applied pressure changes the volume of the trapped gas in the diver, which changes its density and therefore whether it sinks or rises. It is suitable for classroom demonstrations and hands-on student experiments on buoyancy and pressure effects.
FAQs
Q: What is a Cartesian diver used to demonstrate?
A: Buoyancy (Archimedes’ principle) and gas behaviour linked to the ideal gas law.
Q: What is the diver made from and what size is it?
A: Glass, 100 mm length.
Q: Why does the diver sink or rise?
A: Pressure changes alter the trapped gas volume, changing density and buoyancy.
Q: What topic does this link to in fluids?
A: Density, buoyant force, and pressure effects in liquids.
Q: Is this suitable for classroom use?
A: Yes, it is a classic science and physics demonstration item.
