Wow I had no idea about this either! What happens if you break a bulb and clean it up and put it into a plastic bag? Seriously, who has a lot of empty glass jars they can waste to throw away a broken light bulb? I never would have though they had to be cleaned up like this! Thanks for sharing that! We've been buying them for a few years, and I don't remember breaking any. But the stores need to post signs about this!
