Heatswell Coffee Cup is a thin stackable coffee cup which swells to form an insulating collar when hot coffee or tea is poured in.

Designer Scott Amron, who we profiled last year for his Split Ring Key Blank, has come up with another interesting project: the Heatswell Coffee Cup. It’s a thin stackable coffee cup with an insulating band in the midsection which swells to form a cool insulating collar when a hot beverage is poured in.

The Heatswell Coffee cup is non-toxic and recyclable and is approved by the FDA.

Here’s a video demonstration of this cup:
