For this prank, if you have the proper equipment (a rubber band), this is a very easy classic gag to pull off. All you need to do is find a kitchen sink that has a hand sprayer, wrap the rubber band around the sprayer’s handle, and point it toward the front of the sink. Now, when the next person turns the sink’s regular faucet on to get a drink of water or wash their plate off, they will get doused with a stream of water from the hand sprayer. You can pull this joke several times before your victim begins checking for a rigged sink prior to turning on the faucet. After you can’t get them anymore just stop rigging the sink for about 3 weeks, at which time you should start the whole process over.
