Jumping stick is a sneaky trick. Problem is that no string modification is allowed during trick. And no tama modification is allowed as well. You can only move your wrist to have better position during this trick. Start with Aeroplane trick, then throw the can so it rotates for 360 degrees and landed back in the ball. You just work in a slight wrist. It is ideal if you do Airplane with the cup facing to you it then rotates better.
