What do you do to bias the outcome?

Flip it with the right amount of force, like a juggler with bowling pins.

No. You need to put a lot of horizontal torque on it so it never flips over at all.

That’s not a coin flip! I agree that’s a method to achieve the outcome though. If you get the wobble right it’s almost imperceptible.

no audience is going to fall for that...

They do, occasionally it doesn’t wobble enough and looks obvious but done right it’s not perceptible. As a tip do it physically close to someone and catch it high so they have a worse angle to see the lack of flipping. For a real “performance” there is significantly better methods though.

You catch it at the right moment. You learn to feel the right timing by practice.
