This is simple and easy to do project. First of all u need the following materials: Toner, water, beaker or a container, spoon, a strong magnet. Firstly, put the toner in the beaker and then add water to it and mix it with spoon until it becomes a medium solution (shouldn't be thick either to light).
Now time to test it. Spill a little toner on the table and put a strong magnet under the the table and see the shape it forms (the stronger the magnet the better the result). Move the magnet to see the toner move.
