I can extract the absolute last molecule of toothpaste from a spent tube. It's a stupid life skill borne from poverty on my part and bad package design on the manufacturer's part. But I wonder how many gallons of toothpaste, shampoo, liquid soap, etc. go into the garbage, a few drops at a time, because people can't or won't bother to extract the last bits.
When I used to work in restaurants, we used the ridiculous $100 Ketchup Collector contraption shown up top to get the last bit of ketchup out of their glass bottles. Even the plastic squeeze bottles have not made this product obsolete.
Finally I have come across a package design that would enable you to get at the absolute last drop of something!
Intended for peanut butter (but obviously good for a variety of products), design engineer Sherwood Forlee's Easy PB&J Jar concept proposes dual lids, and I covet it intensely. I'm not familiar enough with glass manufacturing techniques to know how much more difficult this would be to make; any experts care to sound off in the comments?
