Here’s a neat advertising gimmick; a marketing company has launched new cans that contain hidden messages.
The resealable aluminum containers by Advercan look like totally normal soft drink cans… until the tab is popped to reveal the high-res graphic or message.
They were created by soft drink junkie, Johan De Broyer, a Ukrainian inventor who’s constantly dreaming up new ways to sell pop. http://www.trendhunter.com/trends/resealable-advercan-hidden-message/
