Go Fishing!

(I've never actually done this, but I think it could work well.)

Need:
-String
-long poles/sticks
-magnets
-paper fish - make these on your own!
-glue

Tie string to the end of a pole and glue a magnet to the end of your string. Next, glue more magnets to your paper fish (magnets as eyes?) and scatter them in a dry bath tub. Then grab a friend and go fishing!
PS. The set up is half the fun - so make some crazy looking fish :)
