position lines of players (or a team) down the court in a straight line, preferably in position order.
The GK faces the back wall away from the court, throws the ball up in the air, rotates, receives and releases the ball to the next player.
The next player up the line drives into space, with a sharp change of direction and also receives, rotates and then releases the ball to the next player up the line.
Get players to see how quickly they are able to move the ball.
To add an element of competition you can have two lines of players racing to move the ball up the court as quickly as possible.
