This is the new "Wear Your Seatbelt" ad the UK is doing. It was started by some guy not hired to do it but, because the cause is important to him, he came up with this idea: and now it's being hailed across the world as a "beautiful" commercial. And now the video has gone "viral" - which means, has become so popular with the general public that people are forwarding it to friends and family on their own so quickly that it has spread all over the world in a very short time.
