Looking for the newest way to waste time at work? Ferrofluid is a unique colloidal liquid made up of nanoscale particles that becomes strongly magnetized when subjected to a magnetic field and this cool new Ferrofluid Magnetic Display lets you experience it firsthand. Just move the small or large included magnets along the outside of the glass bottle and the black ferrofluid in the clear suspension fluid will instantly be attracted to it. You can move it around or watch in amazement as the liquid forms regular patterns of peaks and valleys. Truly bizarre stuff. Check out the video below to see it in action.
