In a world where gravity can be selectively reversed by an amulet, Zephyr has activated his amulet to make gravity repel rather than attract him. He is standing in a field wearing a cloak that is not protected by the amulet. What happens to Zephyr's cloak when he activates the amulet, and what can Mika, who is standing nearby without such an amulet, see happen to Zephyr?

Make your response very short.
When Zephyr activates the amulet, gravity's effect on him is reversed, so he would begin to float upwards because gravity is pushing him away from the Earth. His cloak, however, not being protected by the amulet, remains affected by normal gravity and would fall to the ground. Mika would see Zephyr start to ascend into the air while his cloak falls off him and settles on the ground.
