This is what it looks like in ultra slow motion when a man inside a giant water balloon rolls down a slope

The Slow Mo Guys filmed adult male Dan rolling down a slope inside a giant water balloon using a high-speed camera.

In the first run, the balloon hit gravel and burst; in the second, turning the hole upward made the roll more stable.

Shot at 2,200 frames per second, the video drew attention as a vivid experiment in how a person moves inside a giant water balloon.
