I've only heard of 2 people doing such bizaare experiment but with the use of mineral oil and motor oil. Now I don't wanna use that. So, I had to do some research and look for a liquid medium that is totally non-conductive. Fluorinert - is an electronic testing fluid manufactured by 3M . It is used to immerse devices to test its quality, physically and electrically.
Devices dry quickly without residue to be cleaned.
These 3M Fluorinert Electronic Liquids have good stability, high dielectric strength and are compatible with sensitive materials. For more info regarding fluorinert go here . I have found it. Just the fluid I need. Of course I also want to supercool this liquid.
