You remember when you were younger and you would try to swing as high as possible - so high you felt that if you let go you would go flying up into the air?
Well, this guy did exactly that.
Damien Walters managed to jump off a specialised swing at the right second before somersaulting over the roof of his house and landing on the other side.
Wearing no protective gear at all.
Don't try this at home - as if most of us could, anyway.
