Normally electrostatic sparks are very small ... the air locally can reach temperatures of around 30 000 °C. Try this experiment at home to find out how objects can discharge, as the charge ...

This electrostatic machine will spark from the round discharge electrodes when the crank is turned steadily. The crank rotates Plexiglas wheels that have small metal discs on them. Redistribution of ...

The team had already observed adhesion due to electrostatic charge in previous drop tower experiments. Because only about nine seconds of measurement time in microgravity were possible there ...
