Lightning strikes the United States 20 million times per year. Lightning moves about 30,000 times faster than a bullet. Thunder is the result of the rapid heating and expansion of air caused by a lightning flash. ❓Have you witnessed this? 📸 barrybutler9 📍Chicago #chicagonights #chicagolighting #chicagosearstower #willistower #chicagobolt
