Episode notes
Lightning and Cars
- Josh Clark and Chuck Bryan discuss experiences with cars being struck by lightning.
- They clarify that tires do not ground a car during a lightning strike.
Faraday Cage Principle
- Faraday cages are made of conductive materials, not insulators, which is counterintuitive.
- They protect by distributing the charge on the exterior, shielding the interior.
Franklin and Faraday's Experiments
- Ben Franklin observed the effect with an electrified silver pint can and a cork.
- Michael Faraday later investigated the same principle using a foil-lined room and an ice pail.
