A Cup Sleeve That Expands When Hot Liquid Is Poured into the Cup


(YouTube Link)


Engineer Scott Amron has a clever invention. It's a heat sleeve for a cup that expands when hot liquid poured into is so that the drinker has additional protection from the heat.

Other Amron inventions that we've featured at Neatorama include a keyring/key, leather band-aids, and an art exhibit for which Amron plugged non-electrical objects into electrical appliances.
