After the water is gone, there is no such thing as nothing

Can you talk about what lasts beyond it? One example could be glasses for you. Now the glasses empty. What's in the glass? Once it's empty. What's in it? It's space here. Yeah. Suppose it is empty of arrows. So it is not nothing. It is not nothing because it has the potential to hold something. If it is nothing then I could not put something back in the glass. So it's empty of water then I can put juice in it. So we cannot say it is nothing because the potential for existence of something is there. So actually there is no such thing as nothing. Is it?
