Air is 10°F and the wind chill is -10°F. How cold can your water bottle get?

No colder than 10°F, the actual air temperature.

  1. -10°F, the wind chill
  2. 10°F, the air temperature ✔
  3. 0°F, halfway between

Why: Wind chill is how cold people and animals feel as wind pulls heat from skin. Objects just cool faster to the air temperature, never below it.

Huh, didn't know that: At 0°F with a 15 mph wind, the wind chill is -19°F and exposed skin can freeze in 30 minutes.
