Can molten metal be suspended in air? I wondered if magnets could be used to hold a drop of molten liquid metal in air (not for any particular reason just because it could be done), but was disappointed when a quick Google search showed the metal would lose its magnetic traits before it melted.
Are there any other forces that could be used to suspend a drop of molten liquid metal in air such as sound waves, high pressure air, electric currents, or anything else?
 A: Yes, it is possible to magnetically levitate molten metal. This is not due to ferromagnetism however.  As seen in the below references, the metal sample is placed within a tapered conducting coil, which carries alternating electric current in the ~400kilohertz range.  This sets up a magnetic field gradient inside the coil and causes eddy currents in the sample. The applied magnetic field is excluded from the interior of the sample.  The sample experiences a force in the direction of decreasing magnetic field strength.

A: Molten glass is suspended (and spun) on air jets to form "pre-forms" for molding glass optics. I suspect that the same must be possible for metals.
