This is the first I’m hearing of┬áSmart Lids. The product is a color-changing┬áhot beverage lid that goes from a burgundy (dark red) to a bright red if it comes in contact with extreme heat (above 118 degrees Fahrenheit). It’s a quick solution to knowing whether a cup contains a hot beverage without actually having to touch it or try it against your lips. I know it’s not the biggest of problems, but I like that this solution is so simple. And hey, who doesn’t enjoy things that change colors?

For the casual home user, you can get a box of 40 lids and cups for $40. Or if you’re more of a large volume user, you have several more options to go with.

Check out two videos of how it works after the jump.
