Just throwing out a couple of ideas...
A whisker switch (where a whisker is attached to a microswitch).  The switch could be in a sealed container and the whisker protrudes through the container wall.
An infrared sensor, like the Sharp IR sensor.  The sensor could be sealed in a transparent container.  I don't know if it works through water, though.

Sonar would be very cool.  I wonder if anyone has made a "hobby" sonar system.

actually we also think abt sonar but problem is it gives same value or say arbitary value when it reaches very near to ball it gives same value so it deviate before striking the ball....
