Caution: Contents May Be Hot!
Now here’s an ingenious product: Sydney-based Smart Lid Systems has developed a coffee lid that uses color to let you know when it’s safe to drink your beverage.
If your drink is too hot, the normally-brown lid will turn bright red to warn you that you’re about to burn your mouth. And if it isn’t sealed properly on the top of cup, the lid shows spots of brown to indicate it’s loose.
McDonalds could have used this product a few years ago when they lost a lawsuit for $2.9 million (later reduced to $640,000) to a woman who burned herself and filed suit because her coffee was too hot. And I could have used this last week when I burned the roof of my mouth and couldn’t taste anything for 2 days.
