Generally, glass is more dense than water. (There are some types of glass which are less dense.) You can demonstrate this by gently placing a glass full of water in the sink or tub; the glass will sink, indicating that glass is more dense than water. If the glass were to float, we would know that the glass were less dense.

Try this with plastic cup; the plastic is normally less dense, and will float.
