I am trying to accomplish the very famous magnetic Ferrofluid in a bottle aka office desk toy.
Before anyone suggest to buy online, I would like to make it myself and learn the whole process VS store bought item.
here is a short video of it
Grade 11 chemistry was the last time I studied chemistry.
I would like to create the similar/same toy
My first question is: is ferrofliud thick liquid you can just buy online or do you have to make it yourself using ink toner or magnetic powder etc
I tried making it using ink toner powder mixing it with vegetable oil. The results were not the best but worth a shot, it ended up thick blob and alot of particles it was not clear at all and very hard to see through it.
for the clear liquid I used 50% cleaning alcohol, i tried using water before and it just ended up making the whole glass black. So in short this is the measurements I used and once again I apologize if I forgot to mention anything. I used black ink toner mixed it with vegetable oil, ink toner 10 grams vegetable oil 20ml, and 100ml was cleaning alcohol
Alot of people suggest use magnetic powder instead of ink toner what do you recommend? What different liquids should I be using so it does not mix and stays clear. Some people suggest online make sure you only use water without minerals and iron and many other liquids
