The Soda Seal is a revolutionary update to the standard soda can. It looks and opens like a normal soda can but once opened, you can twist the poptop around and a piece of metal under the lid seals the can back up. The company that invented this wants to use the seal as an advertising spot that you wouldn’t see until you re-close the can. A better use for this would be in beer cans- if you opened up a can of beer and it started to foam up and explode out of the can, simply turn the doohickey and close up the can before you get sprayed with beer. A great idea.
