How a Tiny Glass Bead and Green Laser Reveal Lightning’s First Sparks

See how a green laser and a glass bead smaller than a bacterium let scientists watch lightning-like charge build up one electron at a time.
In this video, you’ll discover:
How researchers in Austria trap a single silica particle with intersecting laser beams to measure its electric charge in real time.
Why the same green light that holds the particle in place also charges it through a two-photon process.
What hidden defects inside glass have to do with freeing electrons and creating tiny bursts of charge.
How this experiment connects to lightning inside storms, microlightning in clouds, and the long-standing mystery of how a bolt actually begins.
Potential real-world impacts for storm prediction, air pollution and aerosol behavior, material science, and ultra-sensitive sensors.
