Sometimes time seems to stand still. At other times, it seems to fly. Masters student Zelf Koelman has created a clock that, using ferrofluid, seems somewhere in between… almost alive, in fact.
Koelman, from the Netherlands, writes that because of how the fluid behaves – presumably when moving toward a magnetic field – its movement looks similar to that of living creatures. While the clock is still in development phase, you can find out more by watching the video below or going to Koelman’s website, here.
