How can one get lead to float? Assume it is in a lump, not made into a boatlike shape, nor carried in a boatlike device.
The first thing I thought of was mercury but there is another answer. Any subsance that conducts electricity can be made to float in a very powerfull magnetic field. Also I don't know if lead becomes a super conductor before you get to absolute zero but if it does it could float in a much weaker magnetic feild.
