World record Diet Coke Mentos fountain

1,300 students have set a new world record for the largest number of simultaneously launched Diet Coke Mentos fountains.

The Belgian city of Leuven was host to the event which saw carbonated fountains launching 30ft into the air as Ladeuzeplein square became a sea of foaming Coke.

Each of the 1,300 students dropped a tube of the mints into a bottle of Diet Coke, producing the famous reaction seen in thousands of YouTube videos.
