Ferrolic is a clock made out of ferro fluid that is moved by magnets to visualise the changing of time. The dynamic of the movement of the ferro fluid gives the clock a tangible and mesmerizing feel to the passage of time.
The only downside is that the clock has a short lifespan of a few months since the ferrofluid degrades after a while and will stop responding to the magnetic fields.
Still, this is a great example of creatively combining physics, technology and a sense of design to produce an item that looks like a piece of art, but also retains it’s original usefulness.
