    (rememebering from secondary school science lesson) when you heat oil the molecules become (agitated?) and start to move around you can see that the oil starts to shift, but when you add something to the oil it reacts starts to cook it, my idea was that the oil is trying to reform its molecules, thats why its starts to bubble and somethings float in it. is it possible that the molecules are staying liquid based but are rejecting the foriegn objects. if oyu understand what i mean please reply i'm finding it harder to writethan speak my theory.

    If I understand correctly, you are trying to explain why a small piece of food dropped into hot oil bubbles and floats on the surface.

    My explanation is that the oil stays liquid at a much higher temperature than the boiling point of water. When you drop the potato chip or whatever into the oil, the water in the potato flashes to steam, generating a lot of steam bubbles. The bubbles cling to the potato chip, keeping it afloat.

    It's clear the OP is confusing macroscopic observations with molecular behavior. Maybe trying to apply kinetic theory or chemical reactions to the observed behavior of something dropped into hot oil. If we had a clearer question we could provide a better answer.
