"3M™ Scotchshield™ Ultra Safety and Security Window creates an
impenetrable window. This tough, new dimension in window film
technology provides property and personal protection against crime,
violent weather and accidents." - from www.3m.com
3M the company that makes post-it notes also make a whole load of other products. In a recent marketing campaign in Vancouver they sought a strong image for their security glass. They modified a bus shelter and fitted their security glass and filled it with real bills! Many have tried to gain access with golf clubs and baseball bats but obviously the glass remains intact! (although other sources say that there was only $500 of real currency, the rest is fake, which i think is more believable. A security
guard was present for the duration of the promotion. People were told
they could only use their feet and would not get to keep the money if
they were successful.)
Hmm.. if only my money album was made of that material.. i wouldn't care if it was laying around for people to see
