So the coffee cups and lids we drink out of tell us "Careful! Beverage is Hot!" But - just how hot is it?! There is nothing worse than burning your tongue so badly on your latte that you can't even taste the rest of the drink. Of course they make the drinks so darn hot that you can't even begin to drink it for at least 15 minutes! Smart Lids are a new creation that indicate when your drink is of reasonable temperature to drink.

The lids are a "coffee bean" colored brown when the drink is cold, and the color additive allows the lid to change to bright red when at the hottest temperature. The continuous brown ring around the bottom shows you that the lid is on securely.

Hopefully we'll start to see more coffee houses using something of this nature, because I'm tired of testing temperature only to be burned. :(
