Auto Generating Coffee Cup Cooling Collar

Those of you that frequent Starbucks and other coffee shops are quite familiar with the thin cardboard collars that can be slid over your cup to keep your hand from melting. The guys at amronexperimental.com have come up with a much niftier alternative. It’s the Heatswell coffee cup. I has the insulating collar built right into it. As soon as you pour the hot beverage into the cup, it will start to swell, creating a terry cloth like band around the cup. The material is non-toxic, FDA approved, recyclable and biodegradable.

  3. I wonder when they are going to start selling these for a dollar next to the check out similar to the reusable grocery bags phenomenon that has hit.
