Once you've got over how different this idea is, it starts to make perfect sense, which makes it sound a little bit like the smart car we all know and love!

If smelling good is high on your list of priorities yet you're keen to be released from the stresses and strains of actually having to spray yourself with perfume or aftershave (which may not be a terribly high proportion of people admittedly, but that aside...) then this is the product for you.

The invention of two Dutch free-thinkers, Swallowable Parfum is a capsule containing synthetic fragrance that allows you to waft a special scent from within. Artist Lucy McRae and synthetic biologist Sheref Mansy developed Swallowable Parfum by harnessing fragrant lipid molecules that can be metabolised by mimicking the body's natural fat structure to release their perfume through the skin.

But you're not restricted to just one scent, as Swallowable Parfum is cleverly able to respond to your temperature and emotions and change your smell accordingly. How have we survived so long without it?!
