In this video, we learn how to make Ferro fluid. This is a magnetic fluid that you can easily make at home. To do this, you will need: laser jet toner, rare earth magnet, and some vegetable oil. Now, pour the toner into a cup (50 ml), then put 2 tbs of vegetable oil into this cup as well and stir it together until you have a thin consistency. Now, transfer into a smaller jar so you can handle it easier. Now test this fluid by taking the earth magnet and putting it to the bottom of the jar. Now, there will be needles popping out of the fluid where the magnet is! Have fun!
