Question about the solidity of air, water and fire body for the druid.

Are these 3 form amorphous ? and if so what size of openings will they be able to penetrate.

Example : sneaky druid needs to get into house that is locked .. change into air elemental and slip in through keyhole. Turn into water and flow up drain pipes( ewww !)

Greetings all ..

I want to create a bow that can bypass DR of creatures.
Basically I want to create a bow that will be able to bypass DR on a round by round basis.
If I have to spend a round to match the bow to the creatures DR that seems easily acceptable.

So the question is this ... spells and material ... what will I need, and how expensive would it be you think ?
