Thunder & Lightning: The Sky's Electric Lullaby
Storms sound big because the sky is big. This episode walks through what is actually happening inside a thundercloud, and why the rumble that follows the flash can become a comfort instead of a fright.
The science, gently
- Lightning is a giant spark that briefly heats the air around it hotter than the surface of the sun.
- Thunder is the sound of air expanding after the flash; light travels faster, so we see before we hear.
- You can count the seconds between flash and rumble: about five seconds means the storm is a mile away.
Wonder together
- Where do you think the storm is right now, near or far?
- Why do you suppose light always wins the race against sound?
- What would rain sound like from inside a cloud?
Tonight's calm-down
Next rumble, breathe in while the sky is quiet and breathe out slowly through the sound. The storm keeps its distance, and your breath keeps its rhythm. Counting the gap turns worry into arithmetic.
