I have always liked science, my wife and I share that taste.
Many times we have proposed to do home experiments and record them, but given the country's situation, it is sometimes impossible to get the materials (no matter how easy and basic they may seem) from me, I have brought you my favorite.
The materials that we will need are the following.
* Printer Toner.
* Cooking oil.
* Neodymium magnet.
They just have to mix a little toner with cooking oil (the proportions vary depending on the viscosity of the oil they use) but it is not decisive either.
The idea is that our "Homemade Ferrofluid" has the highest amount of toner, but without losing the properties of a liquid.
You can take the following video as an example to follow.
I know it is in English but only as a complement to guide us, all you need is in the materials!
