The use of a sink / float separation tank is especially useful in the recycling PP/PE films and PET bottles. In the case of PP/PE films, PP/PE films have a density of around .93 g/cm3 which makes it float while various contaminants such as dirt, rocks, metals, and glass will sink to the bottom where it is collected to removed via a conveyor system.

What is Ferrofluid?

One experiment you might like to try is to make a sink/float separator. Take two strong magnets and fix them to be about a centimetre apart, attracting each other. You will need to fix them strongly so they do not meet as there is a danger they could shatter. Put some ferrofluid into the space between the magnets and it will form a plug of fluid.
