A plastic bag made out of plastic bags that's stronger than its constituent parts and reusuable for shopping trips? How did we not think of this before? While there's been a green movement recently to upcycle "junk" or "trash" into something usable, like old t-shirts into grocery bags, the idea was always to turn something into something else entirely.
