A recent marketing campaign in Vancouver, 3M sought a strong image for their security glass. They modified a bus shelter and fitted their security glass and filled it with REAL BANKNOTES. Many have tried to gain access with golf clubs and baseball bats but obviously the glass remains intact! This is what you call having faith in your own product...
3M was so sure their Security Glass was unbreakable, they put a large stack of cash behind it and shoved it in a bus stop. Great advertisement, right?
Actually, it was only $500 of real currency stacked on top of fake money, and people could only use their feet to try to break it. A security guard was present to make sure no one broke the rules and that people couldn't get to keep the money if they broke it.
Nevertheless, a glass that can stand a double-footed kick from a man with a 30 foot head start is impressive. Don't you wish your iPod screens were made out of this?
