Drink Beer and Save the Planet

Koozies keep it cool.

Here's the science:

• Condensation occurs when water vapor condenses to form liquid droplets.
• Warming occurs when water vapor condenses to form liquid droplets.
• Condensation = Warming
• Ergo, condensation warms your beer.

Here's something else to consider on these hot summer days: "Water vapor and carbon dioxide emit infrared radiation." - Oklahoma Climatological Survey, Earth's Energy Budget Part 2

Moreover: "The globally averaged absorption of outgoing IR radiation by water vapor exceeds that from all other greenhouse gases combined." - Physics Today

Protect your beer. Protect our planet. Use a koozie and save the world!
