Ferrofluids were first invented by NASA and are mainly used for rocket fuel. The so-called ferrofluid, as its name suggests, is a liquid with a magnetic reaction. Because it can be made of fuel plus tiny magnetic particles, it is very suitable for use in engines in a gravity-free environment, so that only a simple magnetic field is applied and the fuel can be magnetically pulled in a specified direction, thus solving the problem. Fuel flow problems in engines in a weightless environment.
However, recently Nike has picked up this seemingly tall, cutting-edge material and used it to make a pretty amazing promotional show for its latest Kevin Durant sneakers.
In fact, the production of ordinary ferrofluids is very simple, you only need to mix the nano-scale magnetic materials and particles into the carrier liquid to form a suspension. The magnetic material particles are coated with a compound to prevent them from agglomerating unless exposed to a strong magnetic field environment. When this material encounters a magnet, it exhibits a corresponding magnetism and agglomerates, even moving with the magnet. However, this effect is only temporary, as long as the magnetic field dissipates, the material will lose its magnetism and return to its still liquid state.
Nike’s show was done by a design studio called Guild. They placed a simple black sneaker on a seemingly inconspicuous metal showcase and showed how the dark ferrofluid reacted to the movement of the external magnet. It must be admitted that this is a cool way to attract people to talk about a super expensive sneaker. Watching the movement of ferrofluids on the surface of sports shoes from the top to the bottom like a wave is still very visually impactful, and it will undoubtedly attract many people to take pictures and share them on social media. Obviously this is Nike's Purpose - virality through social media.
It should be noted that the shoe on which the ferrofluid crawled up was actually a replica of the 3D printed Kevin Durant sneaker. This 3D printed sneaker shows every lace, seam and crease in great detail. At first glance, you may not see it copied. The reason why 3D printed shoes are used is because a strong magnet is installed inside to control the movement of the ferrofluid.

In fact, the principle of this display is such that the Guild team placed 3D printed plastic shoes over a tank containing black magnetic fluid material. This plastic shoe is hollow, with two powerful neodymium magnets installed inside, and these two magnets can also move back and forth on the track inside the shoe, which can pull out the ferrofluid from the slot and produce some very exciting Amazing geometry. As the magnet moves, the liquid rolls up and down the surface of the beautiful shoe, creating seemingly impossible spikes and anti-gravity flaws. This is very visually impactful, it looks almost like a weird creature trying to eat shoes.
This fun show is at the door of Nike's Niketown NYC store in New York. If you're nearby, take a look.
