Mineral oils

Might you know where to buy mineral oils that would never dream of conducting electricity?

Say, maybe like fluorinert?

You do realise that to fill up a 5 gallon bucket with flourent you are talking $1000+ last time I checked.

flourinart is extrewmemly expensive 500 a gallon for the cheapest version last time I checked. An alternitive would be pu\re mineral oil which should be availible at most drug stores. The cost of pure mineral oil would be much less however at low temperatures it becomes sludgy and much less viscous than at room temperature.

Alright, but I havn't found anyone selling fluorinert unless a 100ml bottle for a rediculous price of 67 dollars.

Any other alternatives?

Where did the folks on octools.com get their fluorinert for their submersion demonstration?
