ELI5: Where does new water go when it enters a container that already contains some water?

While giving my daughter a bath, she asked if water sinks or floats and I wasn’t quite sure on how to answer. Where do the new water molecules end up when it joins with other water?

You can answer your daughters question through a simple experiment. Add dye to the water you will pour in then pour the coloured water into the other bottle filled with plain water. You’ll see some interesting patterns form as the water continues with the same momentum then eventually all the water will be the same colour.
