            sand and water are two of the most strange and interesting substances on the planet, property wise. they do all kinds of weird stuff.

                    It’s called ferrofluid. It’s a magnetic liqued that can be used as a cooling agent (sometimes in speakers!). It’s basicaly a liquid vertion of iron filings in this vid – it goes where the magnetic fields are (the two corkscrew point things are big electromagnets).

                        Hi Daftfader ,
                        Thats really cool , i could watch those things for hours . Much better than a lava lamp . Yep we are all followers of the circle of life , never break the circle as it would just be a flat line then and what fun would that be !!!! .

                        Im good mate but ill be away for a week on a course , so have to put my serious head on . I just hope i pass , but then if i dont i dont ……tell my mum i did my best lol .

                            Thanks mate , i hope i pass with flying colours . If not you’ll hear of an accident with a fire engine and a Mungo that pissed in the front seat , nicked the wheels and set fire to the fucker and ran off into to the sunset going …H….Ha…..Haahaahaaa …………hhhaaaaaaaaaaaaaaaaa lol

                                The Japanese lady is making this happen varying the magnetic field by passing complex electric signals through it. it must take a lot of complicated maths to work this out, then sending the signals from a computer into a digital to analogue converter and then to the electromagnets, which also act as a feedback sensor as the ferrofluid going past them generates other electric signals..

                                She studied physics at normal graduate level, then fine arts at post graduate and another course (it looks like she has not just one but three University degrees) and is a Professor!

                                Even then it took about 7 years from her first concept to make those designs..

                                      well she is obviously a clever plus talented lady , see physics can be fun . If only my teacher at school had shown me this i’d be Mungo the magnetic manipulator !!!! . Sounds like some kind of super hero , but no i’d be making ferrofluid shake its stuff . Love stuff like this .

                                            I guess this ferrofluid set up wont be in the shops for a whille then , shame its great . Yep Daftfader our General Lighting is one intelligent man , has the info alright . Great mix of people on PV , and all good people as well 🙂

                                              not as clever as the Japanese lady – I can just about understand how it is done, the actual work put into it is immense and the maths would be beyond me.

                                              With regard to commercial applications, I notice that very little of the real technical detail is being divulged (such as proper scientific papers etc) – I reckon some big company is sponsoring her and her uni and must have some sort of plans for up for the technology..

                                                Fair play i could see why , certainly would have good applications for entertainment . However how knows what else could come out of this , maybe the worlds first motor driven by this ferrofluid . Im sure there are many applications for this , ill guess we will have to wait and see .

                                                  It’s allready being used in loud speaker driver units as i mentioned .. allso in special liqued cooling systems for computors now as well
