Soda Cans With Hidden Messages

"A Ukrainian inventor, Johan DeBroyer has created an idea for a re-sealable aluminum soda can which features hidden advertising messaging. The ingenious new can appears like a standard soda can -- until it is popped open.

When the tab is turned 180 degrees, the can becomes re-closed with a water-tight and gas-tight seal, revealing a full-color, high-resolution advertising message through the tab opening.

The vast potential for the new soda can is proportionate to the fact that there are 250 billion soda cans consumed annually."
