I don't know how I have lived this long without knowing about this prank!

It's executed to near perfection in the video, except for one surprise at the end that may have turned the tables a bit.

The set up is pretty easy if you can do at least one decent magic trick as a hook.  These guys use a simple card trick, then once Benji is hooked they reel him in with just one more.

Fill a bucket with water and have your victim pin it to the ceiling with a broom handle.  Tell them that you are going to make the water in the bucket disappear, and wait.

DONE!  The water holder has no choice but to eventually let the bucket down and get soaked . . . unless you have cat-like reflexes!
