A new sniff-screen technology has been released by the BBC. It relies on the screen interacting with the speakers. Regular computer speakers are used to generate impulses at certain high frequencies which in turn create resonating waves. When these waves interfere with the screen, a phase change occurs that leads to protons breaking down in leptons and quarks. This creates an artificial smell that you can smell while sitting at home and using your computer.
To try it out make sure your speakers are plugged in then move the mouse over the cheese. Wait for 1 minute then sniff the screen. You should then smell the cheese. The smell should be strong and clear. If you’re having problems getting the sniff-screen technology to work please leave a comment and I’ll help you out 🙂
