The Japanese are working on brining us the latest in the Mobile phone industry! The Smell-O-Phone. Using a complex set of microchips, it will be able to break down the properties of a smell, and send that across the phone network to another phone to share that smell.
They see practical uses being in Medical Use, being able to distinguish the type of injury by smell in a car accident. I see the more likely uses to come from people wanting to prank their friends and let them share in the joyful noises and the resulting oder from their lower regions. Or even better, having a phone that cops an attitude because it doesn’t like your breath!
