COLUMBUS, Ohio (WCMH) — Storm Team 4’s meteorologist Liz McGiffin caught up with COSI to talk about the science behind lightning.

Because it’s a little challenging and dangerous to learn about the properties of lightning during an actual storm, we got a Tesla coil out to discover how clouds can generate an electric charge.

You can watch the demonstration in the video player above.

COSI is currently closed for annual maintenance, cleaning and exhibit enhancements, but will reopen on Saturday, October 1.

This fall, Pterosaurs: Flight in the Age of Dinosaurs and Doc McStuffins will replace the traveling Cuba and Marvel: Universe of Super Heroes exhibits. Doc McStuffins will be open starting October 1, and Pterosaurs: Flight in the Age of Dinosaurs will open on October 15. Both exhibits are included with general admission to COSI.
