Treat people as if they are what they ought to be and you may help them to become what they are capable of being.

NICE saw a tv show where they were talking about making transmissions with this stuff in them.. when its in neutral the magnet if off and liquid in fluid state.. when changing to drive the liquid becomes solid.

HERE check out another video

I forgot how, but theres a way to make the fluid sound active, and it moves with the music.

a simple way would be to hook up an iron-cored electromagnet through a diode to an amplifier, thatd probably give the desired effect.

That stuff is pretty cool, wish I experimented with it in high school...
