Zephyr is wearing a loose-fitting necklace while standing upright. If Zephyr does a handstand, what happens to the necklace?

Make your response very short.
The necklace, being loose and subject to gravity, will fall towards Zephyr's head when he is upside down. Gravity pulls objects towards the Earth, so when Zephyr inverts his position, any object not secured to his body will move downward relative to the pull of gravity. Therefore, the necklace moves in the direction of his head, which is now the lowest point.
