Counting seconds after lightning flashes brought physics to life for me.
The delay shows how much slower sound travels compared to light.

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.
