I put beautiful bottles out with colored water as part of my decorations for each holiday. I can't figure out how to make white so I can have red white & blue for the 4th of July. Does anyone have any idea''s how to turn water white?
First, the bad news—As there is no white dye, using a pigment is the only practical "solution" to the question. The problem with pigments is that they will settle to the bottom ultimately.
However, the "Wilton" company makes, and markets baking materials and supplies. One of their products for whitening icing, butter, and edibles is a food colouring "whitener" made from titanium dioxide. It is not organic and non toxic since it is made for human consumption. Finely ground TiO2 should stay in solution for quite a while before settling. The reviews for it are all positive.

Although it was made to use in baking, it is a water-based liquid concentrate which should satisfy your requirements for display decoration.

I can think of a few options. Some of them may not work for you, depending on how you're using them. (For example, putting milk in a bottle may be a bad idea if it's out in the sun all day.)
- Use milk instead of water.
- Add just a bit of milk to the water.
- Add some white, water-based paint to the water.
- Instead of water, fill the bottle with a white non-liquid like white rice, white sand, or even shredded or crumpled paper.
- Paint the outside of the bottle white, instead of relying on the color of the liquid inside.
- Paint the inside of the bottle white.
