5 LIFE HACKS BASED ON SCIENCE

Hey, great video !
I always thought vegetable oil was nonpolar because of this "like dissolve like" thing but recently I watch a video of "static charged object" (sorry i'm french) deflecting a stream of water, and a stream of oil was deflected too, which doesn't make sense if it's nonpolar !
Since vegetable oil is mainly composed of oleic and linoleic acid, which are both polar (acid are usually very polar) 

Acetone is polar too, look at the molecular geometry, there is a higher electron density around the oxygen atom than the 2 methyl groups !

Am I missing something or this polarity explanation is wrong ?
