Why do hockey goalies sometimes bang their sticks on the ice while the puck is on the other end of the ice

Hockey goalies sometimes bang their sticks on the ice while the puck is on the other end of the ice for several reasons:

Communication: The banging sound can be used to communicate with their teammates, especially when they have a limited view of the play. For example, a goalie may bang their stick to signal that they need help from a defenseman or that they are ready for a pass.
Distraction: The banging sound can be used to distract the opposing team's players. This can be especially effective if the puck is in a dangerous area and the goalie wants to give their teammates more time to get into position.
Rhythm: Some goalies find that banging their sticks on the ice helps them to stay in rhythm and focused during the game. It can also help them to channel their energy and stay alert.
Superstition: Some goalies believe that banging their sticks on the ice brings them good luck or helps them to perform better. While there is no scientific evidence to support this, it is a common superstition among many goalies.
Frustration: Occasionally, goalies may bang their sticks on the ice out of frustration, especially after giving up a goal or making a mistake.
