and that is the reason why I don't like mercury. but if you put it in a sube, wouldnt it look like its a wire with clear insulation, but silver instead of the common copper? seems ridiculous to use a toxic substance in place of a green alternative. and no im not on the ion kick again, but instead just saying why use it for wires when you could just string some al wire through some plastic tubes, heck, even melt some al down with a crucible and pour it into tubes so it looks like a liquid...
