Generally speaking, an object will float in a fluid if its density is less than that of the fluid (densltyemass/volume).
If the object is more dense than the fluid, then the object will sink
. For example, an empty bottle will float in a bathtub that is filled with water if the bottle is less dense than the water.

Why does a crushed bottle top sink in water?
When we put the cap on the bottle,
the hot air is trapped inside the bottle
. When we placed the bottle in the ice and poured cold water on it, the air inside the bottle began to cool down rapidly. The cool air exerts less pressure than hot air, therefore the air pressure inside the bottle began to decrease.
