Three hundred microliters of ferrofluid
Ferrofluid kit
Three hundred microliters of magnetic liquid, sold to speaker builders who use it to pull heat away from a voice coil. It does that job well. It's also black liquid that grows spikes when a magnet comes near, and that's why most orders don't come from speaker builders.
