Comments: A small nut and a large mass are connected together by a string that passes through a copper cylinder. When you hold the cylinder, the large mass falls pulling the smaller mass to the cylinder. If the small mass is spun in a circle at a high enough angular velocity, the tension in the string will be enough to hold up the larger mass. If you spin the small mass faster, the large mass will rise. If you slow down, the large mass will fall. Not currently available, but easy to build.
