Aluminum Foil.....

Someone sent me an e-mail about aluminum foil. It told about how for so many years the person never knew about these little tabs that are on the ends of the boxes, they are there to hold the roll in the box so when you are rolling out your desired amount of foil or plastic wrap(they have them too) the roll doesn't fall out of the box. I just had to look and sure enough they are there!! I never knew this either. Did you guys know? Let me know....
