Make your own ferrofluid viewing device, cheaper and much better. 3 diff. types

[TheoriaApophasis]

Not shown is the 3rd type (hard to photograph), which shows the inertial plane of a magnet


Ive been experimenting with ferrofluid suspensions for a LONG TIME.

ferrofluid is very cheap on ebay.......ultimately you only need a small vial to make a LOT of testers (people LOOOOVE them as gifts)

Cost to make? About $1 or less EACH.


You need test tubes, ferrofluid, rubbing alcohol, baby oil/mineral oil
sugar and water.

1. type 1, add 5-12 drops of ferrofluid , then add 70% rubbing alcohol
RESULT: Makes very very fine hair like spikes (regardless of the magnet)

2. type 2.......add a large pinch of sugar to test tube 3/4 full with water...shake it.......THEN add 5-12 drops of ferrofluid , then fill to full and cap it.
RESULT: This makes the large teardrop shapes and diff field effects than #1.

3. type 3.....add ONLY 2 drops (NO MORE!) of ferrofluid....then add mineral oil or baby oil......RESULT? This makes an inertial plane viewer "Bloch wall"



TYPE 1 here:


(that one is the best in my opinion<<<)



TYPE 2 here:




Using EITHER type showing the dielectric inertial plane displacing the ferrofluid on the edge of this GIGANTIC DANGEROUS $800 magnet


You cant really see it below, but this is a 6 inch by 2" thick N48 Neodymium, shes a 'killer', a monster.






making them at $1 , Ive made a LOOOOOOOOT of them, people LOVE LOVE them as gifts.


Theyre wonderful field testers, and demo tools, toys, gifts, etc etc.

Thanks. That will certainly help in my experiments.

Thanks. That will certainly help in my experiments.

Highly recommend using 70 or 90% rubbing (isopropyl) alcohol


5 big drops MINIMUM, ...... 14 big drops MAXIMUM of ferrofluid.

Just a note on rubbing alcohol. Avoid all contact with it and never use it to rub on yourself or anyone. There is good evidence it is involved in people getting cancer as it is absorbed through the skin and was found in every one who had gotten that disease. At the least when handling it use rubber or surgical type gloves. I suspect big pharma knows about this and it's just another way they make new customers in the long run. While I know the effects from it are not immediate I strongly believe it is a big contributing factor in this disease based on studies I've read.

Thanks TA for the cool gift ideas

Then I am DOOOOOOOOMED because I use it on my skin, and wipe my face with it every day usually 2 times a day for , heck, maybe 25+ YEARS
