Ferrofluid Magnetic Display
No matter how old you are, surely the child in you still yearns to play. After all, we learn best when we play, and even in the animal kingdom, basic survival skills are picked up when a litter of puppies or kittens (big cats in the wild, too) play with one another. As for humans, here is one desktop toy that you might want to purchase for yourself or as a gift for a good friend, as the $29.99 Ferrofluid Magnetic Display certainly makes for a decent stress reliever – far better than just squeezing and letting go of a stress ball or to blow right into a paperbag, I say!
Touted to be utterly addictive, you will obviously use magnets provided with the Ferrofluid Magnetic Display to make the fluid “dance”. Hand-crafted in the USA, ferrofluid is actually a kind of colloidal liquid that is made of particles less than 10 nanometers in diameter. Whenever they are subjected to a magnetic field, the nanoparticles will form regular patterns of peaks and valleys, and in the world of electronics, those are are used to form liquid seals in order to prevent debris from getting into a hard drive. Have a good time creating artistic masterpieces for yourself and others to admire during those free moments at the office.
