If the double slit were performed underwater?

I know that photons interact weakly with air molecules which is why we have the interference pattern, and I know they interact strongly with say mud so there would be no pattern in a mud pit, though I am not sure if in a mud pit there would be any kind of light that reaches the screen at all. Anyways I digress do photons interact strongly with water cancelling out the interference pattern thus giving us a regular particle pattern instead of a wave interaction? Also are there any other substances where photons interact strongly where you still see a pattern of light but without the interference pattern? Thanks for your time.

I don't think your premise is right. You can interfere light in glass. Underwater would be a bit messy, but I don't see why it wouldn't work - apart from high voltage issues.

Ok but are there any substances where photons interact strongly where you still see a pattern of light on the screen that is not the interference pattern?
