One of the biggest focuses in coffee and marketing anymore seems to be in the realm of cozy replacement. On one hand the existing simple cardboard  sleeves  work  moderately well. The problem is they are just as disposable as the cups they protect, the idea that most people look to is that to change the cup or eliminate the waste of the extra cardboard.

This is a neat concept. there is a heat reactive coating on the paper cup thats blows up to create a barrier as the hot liquid fills the cup. So it looks like a sticker attached to the outside and the compound is  biodegradable. be sure to check out the video after the jump, not only is the compound a bit freaky to watch but it also looks pretty fun too. Be sure to watch till the end, most of the awesome happens then.
