Watch gravity pull two metal balls together

Summary by Krater

Steve Mould attempts to replicate Henry Cavendish's torsion balance experiment to measure the gravitational constant G using copper and iron masses, but finds that electrostatic forces and other factors make it extremely difficult to observe the tiny gravitational attraction.

Answers: Can you measure the gravitational constant G with a DIY torsion balance experiment?

• torsion balance experiment
• measuring the gravitational constant G
• gravitational attraction between objects
• Cavendish experiment replication

What it concludes

• Electrostatic forces and other interference can easily overwhelm the minuscule gravitational force between masses in a DIY setup.
• The torsion balance experiment can yield a rough approximation of the gravitational constant G close to the real value.
