Begin with a split bottom mount. Take the yo-yo and do an underpass. Your yo-yo hand should be in the front. Take your free hand and move it into the double string. The hands should now be switched. Move your yo-yo hand down and under the yo-yo, making the yo-yo do an underpass. Now flip the yo-yo in a somersault (like a Braintwister) one or more times. Dismount by using a Braintwister dismount.
