At any time you can jump into mid-air and do a floating Maelstrom. Jump and press A + B+ C + Z. It helps to swing the Wiimote and Nunchuk Down in mid-air. You can let your character fall to the ground while still holding the buttons. There will be a Force Maelstrom orb floating in mid-air. It doesn't allow you collect any nearby objects or enemies but simply floats there. Note: This may require multiple attempts as the game sometimes confuses it for Aerial Shock from pressing C; or it will start the Maelstrom once you land on the ground, as a regular one.
