Now this is a great outdoor ad, created for 3M Scotchshield by Rethink Communications in Vancouver. They placed fake Canadian money inside two pieces of glass covered by Scotchshield, and passersby were welcomed to take a crack at it. (The money on the very top layer was real, so people were very compelled to attempt to break the glass.) I rarely consider advertisements to be experiential, but this is an exception in my book.
Check out the people trying to break down the glass here.
Thanks to Brand Noise for pointing this out.
