✅ Barometer
Why?
A barometer measures atmospheric pressure (the weight of air above us), crucial for weather forecasting.
Types:
Mercury barometer: Uses liquid mercury in a tube (classic design).
Aneroid barometer: Compact, uses a metal cell (common in homes).
Why Not the Others?
❌ Anemometer: Measures wind speed.
❌ Hygrometer: Measures humidity.
Fun Fact: Falling barometric pressure often signals storms, while rising pressure hints at fair weather! ⚡☀️
