Counting seconds after lightning flashes brought physics to life for me.

The delay shows how much slower sound travels compared to light.

Always lose count before the boom lol.

Tried this as a kid during every summer storm. Made the whole distance thing click in a way a textbook never could. Such a simple, perfect little experiment.

Five seconds between them means one mile away. Losing count throws off the whole calculation.
