Remember the ferrofluid toys we gave away a couple of years back?
Just in case you’re at a loss, this is what a ferrofluid is:
A ferrofluid is a liquid that has really tiny magnetic nanoparticles in it. The iron oxide is magnetite and gives it it’s magnetic properties. The magnetite particles are called nanoparticles because they are really, really small. In fact, they are so tiny that they never fully settle to the bottom of the container and just kind of hang around as if they were dissolved.
Can you now imagine the fun you’ll have with a ferrofluid toy?
The mad scientist behind the ferrofluid toy is back with a vengeance, and he’s upped the ante. He is running a Kickstarter campaign for The Thinker, which is a different kind of ferrofluid display. It is made of plastic, has a friction fit seal, and 3 mL of permanently magnetized ferrofluid inside.
How do you play around with it? Take a look.
I am mesmerized already.
Kyle Haines, the mastermind behind all this, has also created The Inspiration, which is similar to The Thinker, but also functions as a motion lamp with rising blobs. It is even more mesmerizing!
