Making ferrofluid from scratch

I went ahead and mixed the other part with kerosene, and I poured everything. All fluids seemed to overload the magnet, so I decided to try it with a much bigger one that I just got that morning. It seemed to be able to handle both much better fluid, and the peaks were also larger. At this point, I almost ended up playing with him, but I just wanted to show one last thing. I mentioned before it did not become more viscous under a magnetic field, but in general, it was not very viscous at all. It was practically the same as only normal kerosene, despite being approximately medium magnetite.

From all the races I have made, I have noticed that viscosity is actually something very important in sight, and every time it has been thicker, it has been a really bad sign. Sometimes it initially works and looks like a

ferrofluid

, but over the course of a day, it is usually separated or solidified. Most of the time, these lots end up being garbage, but sometimes, they end up being Mr Fluids, which, as I said, can be interesting in their own way. To measure the performance, I transferred everything to a postgraduate cylinder, and became just above 30 milliliters. There was a small loss of all the things that remained attached to the plate, but in general, this was more or less what it normally had.

Now that we have seen what my liquid did, I just wanted to compare it quickly with commercial things. This was just some of the commercial liquids I bought, and this was what I did. The peaks in mine sonsignifiably larger, and in my opinion, they are also more impressive. The size of the peaks depends mainly on the concentration of magnetite in the fluid, and I think mine only had much more. In every race I do, I try to saturate the kerosene, but because this process is still a bit borning, I have not obtained consistent results. This race turned out to be the best I filmed, but I had some that I did not record that they were of higher quality.

For example, in this without filming, the peaks I obtained were absolutely massive. Before doing it, I did not even know that it was possible that Ferrofluid Spike was so strong. However, the process I did was almost exactly the same, and I'm not sure what caused the difference. However, I am working hard to solve it because having a fluid like this would be incredible. Now, returning to the almost empty dish, I put a magnet under it again, and you can see that all these little peaks are formed. I think doing this in a small amount of the fluid is a decent test to see how well it is.

When the fluid is of high quality, it is easy to form small peaks, even when there is hardly anything there. I like to think of magnetite nanoparticles as small pixels where its size will determine the smallest peak that can be formed and its resolution. When the particles are larger and not uniform in size, the resolution is bad and form larger and flavors. However, when they are very small and uniform, they make them really pleasant and small. Now, in addition to simply increasing the liquid on a plate, there are some other great things to do with it.

The first thing is to add water to a vial and then fall in part of the fluid. The kerosene is only much lighter than the water, but with all the heaviest magnetite, it sinks to the bottom. In addition, with all the water around, the

ferrofluid

no longer adheres to the glass. With magnets, I can move it, and make this little toy great. Sealing the vial was also quite easy, and I just had to fill it with water and then put the lid. Now, honestly, I have no idea why, but for some reason, this never ceases to play with him.

At this point, I have had this for at least a few weeks, and I am still playing with that all the time. As a note, I tried to do this with a couple of different commercial ferrofluids, and never seemed to work. Simply smell, I realized that they were based on kerosene, but I think they also included a lot of additives, which ruined it. In addition, as a second note apart, with the ferrofluid of this video, I have decided to make five of these small roads and give them to the spectators. I will send them to any part of the world totally free, and explain how all this will work at the end of the video.

I thought it would be fun to climb it, so I did the same with a bigger bottle. However, when I did this, it was obvious that my fluid was not as good as some of the other races. While still worked and looked great, the beak was not very good, and I also noticed that there were many bubbles trapped in him. This made it seem a little thicker and not as soft as it should have been. However, in comparison, this was another bottle that I used that other lot that shot very well, and you can see how clean it is.

It is just softer without all those bubbles, and also shoots much more strongly. I am not really sure why this lot turned out to be much more bubbly, but it must have had something to do with the surfactant. However, the preparation for both was exactly the same, so I am not really sure why there would be so much difference. Now, changing the gears a bit, another interesting thing with Ferrofluid is that it is commonly used as a lubricant because it is able to stick to things like magnets and create a liquid cushion. With this, the magnet can remain completely separated from the surface and slide very easily.

While I definitely think this is great, what I found was more fun was to use it to make art. The Ferrofluid cushion also allowed the magnet to slide effortlessly on the paper, and as it moved, it left a really small amount. The result of this were some surprisingly smooth lines with extremely clear and precise edges. Then, for the next 30 minutes, most of the kerosene evaporated, and became even brighter. I have never been very good to draw, and what I did here was almost random. But for some reason, I thought these simple designs were strangely interesting. I also tried sometimes doing this with the commercial ferrofluido, but it never seemed to work very well.

There are some other oily additives that make them take much more to dry, and it also tends to bleed on paper. This makes the edges not so acute and also the commercial liquid is more diluted, so it does not look so black. To be fair, this was just a commercial liquid with which I tried this, and there could be another one that works. However, honestly I doubt that, because almost all commercial things contain other oils and additives. It could be possible. Anyway, I think that's all for this project. I am very happy to have finally been able to do Ferrofluid and that somehow, it was even better than commercial things, but there is still a lot of work to do.

My next main objective is to try to make the process much more reproducible and also climb it. However, I am not sure when it would be published, because for the moment, I have finished with ferrofluids. They are incredibly messy and almost everything ended up covering themselves with oily iron. In addition, I have been thinking about the ferrofluids too often lately to the point where I have literally seen them when I close my eyes. It will probably be in something like several months when I have forgotten how bad it is to work and somehow I convinced myself that it is an incredible idea to visit again.

Anyway, with everything that is said, now is the time of the draw. As I said before, I have done five of these roads and I will give them all free. I will also send them to any part of the world totally free. To have the opportunity to win, all you need to do is use the link in the description, and then, from there, you can get an entry doing some different things. This, for example, can be as simple as visiting my YouTube pages or checking my Instagram. As long as you are there, you can feel free to subscribe or continue, but it is not necessary for the draw.

I will make a drawing for the winners in approximately a week and publish the results here on YouTube and Twitter, and personally I will send an email to all who win. That said, however, I think that is finally for the video. I hope you enjoyed it and that the duration will not kill them, and I will see them in the next. As usual, a great thanks to all my followers in Patreon. Everyone who supports me can watch my videos at least 24 hours before publishing them on YouTube. In addition, everyone in Patreon can send me a message directly.

If you support me with five dollars or more, you will get your name in the end as you see here.
