"The chewing and helium experiment" (as seen on youtube) is part of a campaign called "The viral test" - if you go to
http://www.viral-test.com you can make your own branded film to pass around like we've done here (spot the subtle rainbow TV everywhere). As fake as it is, admit that you had the idea of combining helium and chewing gum at some point in childhood - we all did.
"The campaign has been ordered by Blue film production and created by Rapp France."
