One option is to turn the ice cube tray upside down over a bowl and pour cold water over it so the ice cubes fall out. You can also try hitting the bottom while the tray is upside down. Alternatively, hold the tray at each end and twist it back and forth to free the ice.
Why is my ice sticking to the tray?
Ice cubes break into pieces because the plastic trays become coated with hard-water mineral deposits (calcium carbonate) that settle into nicks and scratches in the cube compartments and build up over time. Water clings to these deposits as it freezes.

How are Icecubes made?
The water first freezes on the top surface, around the edges of what will become the ice cube. The ice slowly freezes in from the edges, until just a small hole is left unfrozen in the surface. At the same time, while the surface is freezing, more ice starts to form around the sides of the cube.
What material is best for ice cube trays?
Stainless steel is a well-suited material for ice cube trays. It doesn't absorb freezer smells or food odors like some more porous materials, and stainless steel is BPA-free.
