Pour a hot beverage like coffee, tea, hot chocolate or soup into this thin stackable coffee cup and watch its midsection swell to form a cool insulating collar – a 100% genuine endothermic reaction.

    I think there’s a Glitch or a few kinks to work out. the best Cut doesn’t mean you won’t have a blob 1 out of 4 times you get your coffee.. I’d have a Laugh every time I’d see the things. They’d probley be littering the roads. they won’t even fit into the cup holder. Sorry, but I’ll look forward to the next version. I’m sure you’re gonna get a handle on it. it seems within reach. Keep working on it. It’ll turn out.
