For two people to fall in love the chemistry between them has to be just right. In his latest video for The University of Nottingham’s Periodic Table of Videos website, Professor Martyn Poliakoff examines the science of Valentine’s Day.

 

This eight minute video looks at why chocolate melts in your mouth rather than your hand, and how roses display that deep red colour so favoured as the perfect gift on February 14. The video has proved a popular one, with more than 10,000 views just 10 hours after being uploaded. It even features Professor Poliakoff — who has become something of a scientific superstar on YouTube —explaining the chemistry of love.

“In chemistry different atoms and compounds combine together to form stable molecules and complexes,” Professor Poliakoff explains. “In the same way, if you get the right two people they will react together and make a very stable combination.

 

“Others may combine as something a bit more volatile. And occasionally you get a pairing that’s even explosive. But that’s what makes chemistry fun — and it’s what makes relationships fun as well.”

 

The Periodic Table of Videos — www.periodicvideos.com — is home to short videos examining the properties of the elements, from aluminium to xenon. The site has clocked up more than five million video views. Its sister site — www.test-tube.org.uk — showcases the work of scientists in Nottingham. Filmmaker Brady Haran is responsible for the sites, creating and uploading videos that have been watched all over the world. 

“We were never going to let Valentine's Day go by without a chemistry film, and it was bit of a no-brainer to make it about chocolate and roses,” Brady said. “As always, Martyn astounded me with the information he can pull from the top of his head, and he is fast becoming a real cult hero on YouTube.

“Obviously people love the way he looks with that crazy hair, but more importantly Martyn also has an uncanny ability to make things simple without dumbing them down. I think just watching Martyn makes people feel smarter.

“Science communicators are always trying to make things easy to understand, but Martyn seems to realise that our viewers still want a bit of the complicated stuff!”
