DALLAS - North Texas was covered with fog much of the last week. As such, meteorologist Colleen Coyle dug out a few tools in the WFAA break room to show how fog forms and why it loomed over North Texas. Check out her experiment!
Want to make your own fantastic fog experiment?
- Small jar
- Warm Water
- Small ziplock bag
- Ice cubes
- Dark colored background (piece of paper, book, etc)
Fill a small jar with warm water. Let the water sit in the jar for 1-2 minutes. Pour most the water out leaving about an inch of water in the bottom of the jar. Fill a small ziplock bag with ice cubes. Place the ziplock bag next to the small jar. Light a match and hold it in the small jar for 3 seconds and then drop it in the water. Immediately place the bag of ice over the top of the jar.
Now - watch the magic! A cloud will begin to form in the jar as the warm, moist air interacts with the cold air from the ice. Place your dark colored background behind the jar to enable easier viewing.
