Anyone know about ferrofluids? ;D
What in the world?
Whoa… What is it?
A ferrofluid is a polarized fluid that you put a magnet near and it will form crazy shapes and such.
I was genuinly scared for a moment
it is just liquid magnets. and they are awesome.
I should’ve known that.
And any substance with iron in it is Ferrous.
iron powder and mineral oil? or something else?
FeO, magnetite precipitated from a complex reaction between NH and a mixture of Ferric Chloride and Ferrous Chloride. The carrier fluid is kerosene and the surfactant is oleic acid.
Was it difficult to make? Very.
how to make it? ; - P
Kinda reminds you of that horror film splinter. :-[
That’s fricking awesome! I gotta show this to my chem class. ;D Thx dude.
That method’s more costly than you think. MICR toner can go above $80 dollars. With the method I used, converting the Ferric Chloride, you’ll probably spend about $20-30 dollars, not including the Oleic acid. Oleic acid’s pricey, but chances are your Chem teacher might have it stored in the back.
