The ultimate slow-mo splash
Over the last four years they've done things slowly but success has come rapidly. Gavin Free and Daniel Gruchy have built up millions of fans risen by filming stunts and then running the footage at thousandths of a second. They've blown up a watermelon, started a water balloon fight with over a thousand people, taken a football right in the face and even filmed Dan vomiting a gallon of milk.
They've had 425 million YouTube hits, featured on The Tonight Show and they're here today with an amazing slow motion This Morning stunt.
Wow - watch the incredible slow-mo footage of Phillip bursting a water balloon over the Slow Mo Guys!
