A passing drill
Put a number of pylons on the goal to goal line.
Each player has a puck.
Player 1 passes to player 2, while player 2 passes to player1.
Both making sure the pucks go between the pylons.
Passing to each other until they reach the other side.
When 2 and 1 get at the last pylon they score.
Player 3 and 4 start when player 1 and 2 have reach the midline.
After making the shots players 1 and 2 skate back to the other site of the rink.
To make it more interesting a goalie and a defender (with restrictions) can be added to the drill.
