Tornado Detector
When traveling in the Midwest during tornado season, motorists may want to use this idea: if the sky appears dark and threatening, turn on the car radio. Tune the radio to the low end of the AM band, 550 kHz. Tornados generate electrical waves that cause static on the radio. One may hear crackles due to lightning strikes and perhaps steady clicking from the car’s ignition system. But if loud constant static is heard, a tornado is near—get out of the car and seek low ground immediately.
