Hi everyone. I'm making a prop for my Halloween display, it is a shelf with light-up bottles on it. The bottles are lit from below by LEDs built into the shelf. The problem I have now is that I need a way to make the water in the bottles slightly cloudy to diffuse the light. Can anyone recommend a way to do this? I considered milk, but I'm afraid it will spoil. Right now I have soapy water in them for testing.
