This champion-approved technique will have you flipping perfectly. Rest two-thirds of your middle finger under the bottom rim of the cup, and make sure to keep it slightly bent. Our expert says this allows greater control during the whole flip because it allows more of your finger to stay on the cup longer; this technique lifts the cup instead of just blindly tapping it, like some sort of fool! For novices, it's recommend the use of both index and middle fingers, as it'll stop the cup from rolling left or right off your finger. Also make sure to keep your elbow and arm both flat and perpendicular to the table. After each flip, you should be ready to flip again if necessary. That's critical.
