About this project
Our kickstarter ends soon, but you can still GET OUR FERROFLUID DISPLAYS AT INSPIRED-DESIGNS.ORG
A New Symbol
I believe ferrofluid is a great icon to represent the 21st century, much in the same way motion lamps are considered an icon of the 1960’s counterculture revolution. People embraced it as a sort of statement to the zeitgeist of that era. That’s how I feel about ferrofluid at this point in time. This is why I created The Inspiration.
The Thinker can be upgraded w/ colored ferrofluid. Available colors are blue and gold.
All of the rewards on this kickstarter are discounted from the expected retail price to show appreciation to all of my kickstarter backers. You guys deserve it. You are awesome for believing in me!
The colors gold and blue are the only options available at this time. More colors will be made available in the future.
Stretch Goal #1 Reached!
If we can raise $75,000 everybody that backs The Thinker reward tier will have the additional option of adding green colored ferrofluid to the display.
Green colored ferrofluid is an upgrade (add $24) just like the blue and gold colors, however it will not be offered immediately after the kickstarter like the other colors, making it an exclusive reward for my kickstarter backers.

Ferrofluid is an example of nanotechnology and when presented in the right manner is very successful at creating interest were there was none before. This is because of natural curiosity. I want to encourage that curiosity as well as the imaginative thinking that comes with it. I want to remind people there's still so much to discover and explore.
"Nanotechnology. The science is good, the engineering is feasible, the paths of approach are many, the consequences are revolutionary-times-revolutionary, and the schedule is: in our lifetimes." - Stewart Brand
Why is Nanotechnology Important?
Nanotech is a disruptive technology. It creates new possibilities and makes things that once seemed impossible very real. Ferrofluid is just one small example of this. Researchers are currently creating other meta-materials that sound like something straight out of a sci-fi movie or video game.
For example, we have created objects that can bend light completely around themselves, making them invisible. We have business suits already on the market that use carbon nanotubes to make the fabric bullet proof. The potential game changing uses for carbon nanotubes alone generates a list too long to post here. New applications and discoveries are being made in this field regularly.
Additionally, nanotech fuels Moore's Law...
Exponential growth is explosive. Every 25 years the processing power of computers grows by a factor of 1000!
My Past Experience
I often collaborate with a group known as CZFerro. CZFerro is a ferrofluid knowledge bank that specializes in ferrofluid displays. Members have been offering ferrofluid displays for sale on the internet for over 5 years and have worked with ferrofluid since 2008. Inspired Designs, LLC will have full access to CZFerro members and their expertise if needed.
Okay, if you've read this far your probably interested in the science behind it. Good for you!
First, I want to highlight the size 10 nm because that is the size of the nanoparticles in the ferrofluid...
What is ferrofuid?
As you can see, ferrofluid is a magnetic liquid.
This is something special because all known magnetic materials lose their magnetization when they get too hot. And this always happens long before the material reaches it's melting point. The trick is to suspend tiny pieces of solid magnetic material in the liquid.
Normally, solid particles mixed in a liquid will eventually settle to the bottom because of gravity. Much like mixing sand in water. But, if the particles are small enough (say 10 nm) they won't be pulled down by gravity. This is because of a force called Brownian Motion.
Brownian Motion is the tendency of liquid molecules to be constantly moving around. As a result, they bombard other particles in the liquid. And when the particles are very small in size this force is strong enough to counteract the force of gravity.
It's a lot like a balloon being bounced around by a crowd of people. The sea of waving hands will keep bouncing the balloon back into the air.
Why does it spike?
The spiking is the result of a few different forces competing with each-other. On a fundamental level these would be the van der Waals force (attractive/repulsive forces between molecules), gravity and the magnetic force.
In this case, the first two forces (van der Waals and gravity) manifest themselves as surface tension and play a very big role in how the ferrofluid spikes.
Obviously, the magnetic force plays a major role in forming the spikes because we only see the spikes when we apply a sufficient magnetic field. What's really happening is we are attracting the magnetic nanoparticles with the magnetic field and this creates an uneven distribution of particles, or gradient, within the ferrofluid. This gradient follows the magnetic field lines and rearranges the nanoparticles in the ferrofuid.
Why does it rise and fall (The Inspiration)?
Initially, the ferrofluid is more dense than the clear liquid and sits at the bottom. But,the ferrofuid changes it's density when it absorbes heat from the lamp at the bottom and becomes 'lighter'. This allows it to float to the top. Then, it begins to cool and it's density changes once again. As it cools it gets 'heavier' and falls back down. Then the process repeats itself.
What are Other Ferrofluid Applications?
- Cooling in loudspeakers for better sound
- Liquid O-rings for making computer chips
- Magnetic hyperthermia for better chemotherapy
- Targeted drug delivery for cancer treatment
Vanessa of Ferrotec wrote a wonderful blog post where she explains these applications and more.

Risks and challenges
As far as research and development is concerned, I feel I have adequately covered everything imaginable. However, it is true that ferrofluid is well known for throwing curve balls. Sometimes there are unexpected snags in the manufacturing process. I have been through this many times over in the past. It would be a lie if I said it wasn't possible this could happen with these new products as well. But, I do have a track record of troubleshooting these issues very well on previous projects with the CZFerro team. I also will take any complaints very seriously and do my very best to resolve any problems as quickly as possible. I will replace anything damaged during shipping free of charge. I will be as transparent as possible with my backers during order fulfillment and keep you updated on the progress as well as any speed bumps that may pop up along the way.
I've watched previous ferrofluid kickstarter projects by others in the past fumble both the R&D as well as transparency and do not wish to follow in their path. This is why I have applied 3 years of R&D before filing for patent pending status and launching a kickstarter.Learn about accountability on Kickstarter
