Glad-Lock Bags “Pigs” and “Angry Bees” [00:30]# Comic book collector John Adams won’t switch from his zipper bags to Glad-Lock bags. But the confident interviewer is about to put him on the spot. What if his first-edition Spiderman comic were to be dropped into a pigsty in either his bag or a Glad-Lock bag with the green color-change seal? To raise the stakes, the sty is wheeled out behind him. The geeky collector now reconsiders. “When it really counts, get Glad-Lock”. Mary Cleary is another Glad-Lock sceptic. She refuses to switch form her bags until she is faced with a challenge from the presenter. What if we lock you in this phone booth (wheeled out behind her) with your bag full of angry bees, or our bag. “You know, change is good”, she quickly reconsiders.
