When e-mails arrive in the future it might not be a noisy ping that tells you about it, but a nice smell instead.
An internet company has come up with some new technology that will let people send smells over the internet.
The smells themselves aren't actually sent through the wires, instead you plug a machine into your computer that sends out a smell when it's told to.
E-mails would have information in them that would tell the machine to spray a smell into the air near the computer.
