Water movement on surfaces makes more electric charge than expected
The team measured the electrical charge and contact areas created by water droplets spreading and contracting on a flat plate of Teflon—effectively simulating the movement of droplets over the surface ...

Electrostatic sparks and shocks
These are non-contact forces, so the objects don’t ... This Van de Graaff generator helps to build up electrical charge so we can see its effects. Electrons are picked up by the rubber belt ...
