Empty Gas Cans?

We’ve all done it before. You’re getting ready to fire up that grill but unsure if you have enough butane. Just in case, you look at the can, which by the way is totally solid and encased in metal. You shake it like polaroid picture for good luck and hope for the best. A better gas can would be the Empty Mark. By integrating a layer at the bottom of the can to appear thru a transparent window, you can easily see when you’re almost out of butane. Smart but does it work?
