IN THE 60'S GLASS MILK AND COKE BOTTLES HAD A SMALL CASH VALUE. KIDS WOULD GATHER THESE BOTTLES AND RETURN THEM TO ANY STORE FOR MONEY. WE ALL BOUGHT CANDY WITH THAT MONEY. OUR PARENTS DIDN'T TELL US TO DO IT.
WE JUST KNEW HOW TO GET CANDY ON OUR OWN. YOU WANT TO CLEAN UP THE ENVIRONMENT? PUT A CASH VALUE ON PLASTIC. KIDS WILL CLEAN IT ALL UP FOR A CANDY BAR.
