Place the transparent gem on a table and spin it clockwise. After a few turns, the gem will stop while you are making a magical gesture and will start to spin in the opposite direction! If it is spun counterclockwise, the stone does not stop… or does it? On a second try, the gem will stop its rotation when spun counterclockwise! It will start to spin in a clockwise direction indead! Two totally different prepared gems & routine included! One stops clockwise, the other one counterclockwise!
