Details

Ferrofluid is made from tiny magnetic particles coated with a stabilising dispersing agent within a carrier liquid. The dispersing agent, known as a surfactant prevents the tiny magnetic particles clumping together, even when a strong magnetic field is applied to the liquid. Instead, when an external magnetic field is applied, the particles, each of which behaves like a spherical magnet with a north and a south pole, experience a torque and align themselves in the direction of the magnetic field. This reaction causes the fluid to form amazing spikes which can be precisely controlled by applying and removing a magnetic field, such as that produced by a Neodymium magnet. Ferrofluid truly is a wonder to behold and makes an incredibly unique gift, just be careful never to let the fluid come into direct contact with a magnet otherwise you will never be able to separate it again! 20ml tube EFH1 grade ferrofluid
