Introduction: How to Execute the Fink Toilet Prank.

Picture of How to Execute the Fink Toilet Prank.

This prank actually involves a mensroom urinal, I don't know why it's called the Fink Toilet but the name dates way back to the alt.shenanigans newsgroup. This prank is quick and easy and sure to leave your victims soaking wet, hopefully in the crotch reigon.

Step 1: Ingredients

Picture of Ingredients

You will need:

1 Bic-type Pen
X-acto Knife
Duct Tape

Step 2: The Pen

What you are going to do is modify this pen into an angled tube that will redirect the water flow from the urinal.

First, discard the tip and ink. Cut off a 2" length of the pen tube.

Second, make a v-shaped cut somewhere near the center of the tube as pictured.

Third, make a narrower v-shaped notch in whichever end of the tube is longer.

Last, bend your tube and tape it up. I used clear duct tape to help camoflage it.

Step 3: Know Your Urinal.

The narrow notch in the end of the tube is there so you can squeeze it together and stick it in one of the holes at the top of the urinal. Hopefully your notch is the right shape to hold it in there good and tight. Go for one of the holes closest to the center, that's where the most pressure will be.

The length and angle of the tube may have to be suited to the particular urinal you're going to use it on.

When your victim flushes, a good portion of that water is going to shoot straight at him. I recommend you test it out first, there are a few tricks to getting it right:

-If the stream is too weak (lol) you may have to plug some of the other holes. Wadded up toilet paper is good, but can take some time. A quick method is to come prepared with some little corks you can get at any hardware store. Careful, too much pressure will blast the delivery tube right out of the urinal.

-If you still can't get enough pressure, sometime the plumbing will have an exposed adjustment that you can loosen to get more pressure. You may need a crescent wrench or a large screwdriver to open up the valve.

The next-to-last but most important step is WASH YOUR HANDS! You just touched one of the dirtiest objects on the planet.

Lastly, sit back and watch the fun. I myself do not have the guts to film a random victim getting nailed by this, but if you do, youtube the video and I will link to it.

Variation: Use three tubes and point some of them at an angle to hit people standing at other urinals.

I will get some more pics up of the urinal and maybe a video of it in action soon.

Ok, this would be funny but I would be kinda creeped out if I step into a toilet and someone is sticking cork and 2 inch rolls of plastic into a urinal....

video camaras! ewwww. lol

Ahh, that's terrible. Film someone at a urinal?! Are you nuts or just perverted? That would be a good way to spend the night in jail.

ahcmachinist (author)royalestel2007-05-29

I'm not talking about filming a person's privates, just their reaction to getting sprayed with water. It's not like someone standing at a urinal is going to turn around with their weiner hanging out...

Dude, i did this and taped it, and i sent it to AFV so if u see it and it wins 10000$ ill give u 10$ :P

coolz (author)Lt. Duct Tape2008-06-02

never seen that vid before

That would be so funny. I'm rofl from the idea... Or if they fall and it shoots them in the mouth

It depends on whether they flush then zip or not lol This is a funny kind of cruelty...

royalestel (author)ahcmachinist2007-05-30

Ah, so you just film from the shoulders up then. You could get away with that a la Candid Camera.

jeffconnelly (author)2008-04-07

How about putting it on a motion-activated toilet?

coolz (author)jeffconnelly2008-04-26

well, youll be the first victim if you try that

jeffconnelly (author)coolz2008-05-31

well, you'lll know it's coming, so you can put on a raincoat or something

Kaelessin (author)chuck norris2008-03-31

Too bad the kids at my school don't flush...

musicalbee2003 (author)2008-03-24

Did this in a school toilet. It didn't work, but when I checked on it a few monthes later, I realized the janitors don't actually clean the toilets...ewww:P

Monkey T. (author)2008-03-24

man, i can't wait to try this in the airport, muahahahahaha!!!!

I live in japan and most Japanese homes have a urinal. Since I have no access to a public men's room for obvious reasons, this gives me a good way of getting back at a certain guy for zip-tying random objects to other random objects around my house. This just fills my little heart with glee.

easyrider1 (author)2007-12-31

this is so darn funny i just about have tears.unfortunately i'm one of the few(prob.5%)guys that actually flush(and wash hands) when nobody is around.but i do use my foot to flush(i know where the previous persons hand was).oh, and this is not the nastiest place to put your hand,think dog mouth ,where has his tongue been(tasting poop,cleaning nads,licking po po,you get the picture).if your girlfriend lets her dog lick her face,you know what your kissin'.on another note if somebody gets me on this trick better keep a straight face cause the first person that looks guilty or laughs is gettin' a round house kick to the head.but hey,great instructable

pls don't roundhouse to the head, that really can kill if you hit the right spot. I was hit in the head (just over the right frontal lobe...right frontal lobe has something to do with you being conscious) and I was passed out but still walked to the other side of the room and was standing over there when I woke up 5 seconds later.

themasteroftheuniverse (author)2007-06-16

karen608 (author)2007-06-01

Ha! Made me laugh. But if you do this at walmart nad a guy doesn't flush.... all the fun gone till next poor guy that shows up. I won't be trying this at work because i like my job as janitor. Ah, i wish i could though.

instructa-fan (author)2007-05-29

you're married and pulling toilet pranks? Not to mention talking about filming/invading a males time and place of relaxation/piss place!

Well, I came up with this in high school, which was about 10 years ago. Tell me you wouldn't laugh at this....come on!

I know I WILL laugh cuz i'm gonna finish it up tonight and go to wal-mart tomorrow.

instructa-fan (author)2007-05-28

HINT HINT HINT!!!!!! Point the tube slightly towards the exit cuz most people flush on the way out.

BLACKROD (author)2007-05-27
