Ferrofluid 2.0 OZ

What is Ferrofluid? In short, Ferrofluid is a liquid that responds to magnets and magnetic fields. The longer answer is ferrofluid is an extremely fine powder, coated with a soap-like material called a surfactant, suspended in a mineral oil liquid base. The resulting magnetic suspension is called a ferrofluid. When no magnetic field is present, ferrofluid behaves and flows like a normal liquid. However, when a magnet or magnetic field is introduced, the ferrofluid is attracted to the field. Spikes then form along the magnetic field lines when the magnetic surface force exceeds the stabilizing effects of fluid weight and surface tension.

Ferrofluid Description:  The term means "iron" in Latin from which the word comes from.

Ferrofluid was developed by a NASA engineer as a way to keep fuel moving through the lines in the weightlessness of outer space 

Ferrofluid is basically an oily based substance with very small (think nano) particles of an iron based magnetic substance with a little bit of a surfactant & there you have it, a substance that will disperse itself evenly in the fuel and when subject to a magnetic field will allow that fuel to flow through the gas lines in space.

What does this mean to you?  As a budding scientist of perhaps someone that just likes really cool stuff it is a great toy be careful in can be a little messy. (Probably not for children younger than 12) Ferrofluid allows you to actually see some of the effects of a magnetic field.  

There are many recipes for ferrofluid but the basic one runs about 5% magnetic solids (metal particles), 10% surfactant and 85% carrier (oil based product).

Please take care when handling ferrofluid. Besides being fun to play with, it also is capable of staining everything it comes into contact with. Please make sure to take care when using it.

Ferrofluid should never be used for applications involving loudspeakers. Ferrofluid can be hazardous or even fatal if swallowed or if it enters airways. Ferrofluid can cause skin irritation or serious eye irritation.
