Have you tried the new technology with which u can get a smelling sensation from Sound. Yes! you read it right. Smell from sound.
It has been recently discovered that a particular sound when emitted at a specified frequency simulates our sense of smell and we can get various kind of smells from these sound waves.
This app emits a sound which will create a smell like that of a Rose. Give it a try.
PS: Ignore everything written above. This is just a prank.
The button when clicked will emit a sound of fart and no supernatural waves like mentioned above, like the user would be expecting. :-)
This description is also a part of the prank, for those who directly download it. It works better for those who receive the app as a link from friends because they haven't read this. ;-)
