i usually tilt the ear that has water in it towards the ground and jump and and down really quick. if that dosent work then i do the alcohol or jaw thing mentioned. usually one of those works for me.
I used to lay a towel down on a pillow and lay my head to one side on the towel. If you wait a minute or two it drains out on it's own. Then switch sides and repeat. That usually works. Rubbing alcohol works too. HTH!
