Picture of April Fools Toilet Prank

This April Fools joke is probably my personal favorite.
This joke is more for guys.

Step 1: Supplies

Picture of Supplies

1. some clear plastic wrap
2. 1 roll duct tape
3. 1 pair scissors
4. A toilet

Step 2: Preparation

Picture of Preparation

A. First, lift both of the toilet seats up as in picture 1.

B. Next, you will need to cut five duct tape strips about 2" as in picture 2.

C. Then, place a sheet of plastic wrap lengthwise on the toilet as in picture 3.

D. Now, using your duct tape strips, tape down the plastic wrap as in picture 3.

E. Finally, close the first lid and admire your work.
The finished product should look like picture 4.

Step 3: The Surprise

This will provide a big surprise for the next male who comes along to urinate.

Do you have a great toilet prank idea?
If so, then write your idea in a comment on this Instructable.
And probably you will find your comment on this list.

f you take the lid off the tank you can take the hose and point it out the back or front of the lid. Be sure the hole is clear of obstructions and that it isn't obviously sticking out. When someone flushes the toilet, water will squirt out and not stop until the hose is returned to the tank and the tank fills up. Obviously, this is best done at a friends house or (the best) at a bar/bowling alley.

If done in a public place, some people like to give a "courtesy" flush. This will result in them getting showered with water (back of tank setup) or sprayed in the back (front of tank setup).

I've done this one for years and it works great. From Harleydreamer

Put folded ketchup packets under first seat when sum1 sits down big explosion
From cheezydog10

Heres another trick get party confetti things and take out the pull fire cracker and attach the string to the toilet seat and tape the fire cracker to the toilet put the toilet seat down when a guy goes to pull up the seat to pee BANG! From struckbyanarrow

Get gelatin and boiling water,
Mix it together real good,
Put in toilet and stir with brush!

You have to scoop out your poo!!!
From Duck-Lemon

Baking soda in the bowl, and vinegar in the tank.
When they flush, it produces CO2 and overflows. From bruno13069

You could always make it so that it is impossible to flush (maybe disconnect the flush handle from the inside). Then you could make fun of them for "breaking" your toilet.

You could also add some red food coloring to the water tank to give the flusher a surprise when he/she finishes. You could also make it brown and act disgusted when they leave (make sure to create a huge scene). These are just some ideas I thought of sitting here looking through the April Fools pranks.
From Dr. Paj

You should do this in a public bathroom, and wait in the next stall for someone to go. From Domindude3

In college I used to put a couple throw pops (like they sell for kids on 4th of July here-you just throw them on a hard surface for a bang) under the toilet seat risers, so when someone sat down you would hear an explosive sound echo from the dorm bathroom! Guaranteed every time that if they didn't need to go before-they definitely had to go after!
From inquisitive

Take all the light bulbs out of the bathroom and leave the seat up, that ones for the ladies, although i wouldn't do that to my girlfriend unless she did something really bad to me.

Or try putting Potassium Iodide in the bowl, then a bunch of 30% Hydrogen Peroxide and a cup or so of liquid dish detergent in the tank. The Potassium Iodide catalyzes the separation of the Hydrogen Peroxide (H2O2) into water, oxygen, and heat... and lots of it. The detergent captures the oxygen and steam in bubbles. This means the toilet becomes a volcano of hot foam.

WARNING: the foam is very hot, and goes everywhere. It's not like they cant run from it, but it could scald, and will take quite a while to clean up.

Here are a few toilet and bathroom pranks: 1. take a milky way bar, squish it up, and make sure there is a person in the next stall. slip it under the dividing wall and tell them if they could give that back to you. 2. stand up, when there is someone in the next stall, and take a Clementine, grunt a lot, the drop the Clementine in. finish with a satisfying sigh. 3.take a mirror ( and don't be a pervert), and use the mirror to look at the other person's eyes. Then say Peek a boo!! HILARIOUS!!! :)

Put yellow food coloring (or better, pee) in the tank so when he/she flushes the toilet, it looks as if more pee comes into the bowl! :D (I found this on some fourms)

foxtrot4697 (author)vailo2009-07-03

Tomasauk (author)foxtrot46972011-09-10

Wesley666 (author)vailo2011-04-01

misterchrischan (author)2009-01-21

THE ULTIMATE TOILET PRANK: i call this one the "top bunk". best to do at an enemy's house. 1) remove lid from tank. 2) defecate inside top tank. 3) replace lid. 4) dont flush now! leave that "duty" for the next person. 5) enjoy the satisfaction of knowing that the bathroom will smell worse and worse over time, and the water will always be dirty. WARNING: THE VICTIM WILL HAVE TO REPLACE THE TOILET!

That's called a double decker. It's always fun to do this in public toilets...

mean yet funny i like it

Wesley666 (author)2011-04-01

Do a double decker. Poop in the tank, surprise when the next person flushes...

napalm008 (author)2008-04-09

reusesave (author)napalm0082010-04-02

nice one

The Jamalam (author)2010-04-02

If you use a large amount of clear washing up liquid and put it into the water at the bottom, when the person flushes foam will rise up very fast and pretty much destroy the bathroom.

Huntman00 (author)2009-11-11

if u put food coloring in the tank so when they flush it will turn that color..........will it stain the bowl

red-king (author)Huntman002010-03-18

 it shouldn't if it's just food colouring.

Huntman00 (author)red-king2010-03-20

ur shure??

red-king (author)Huntman002010-03-20

 I'm not completely sure... but foods coloured with food colouring (such as cake icing, candy, etc.) don't stain dishes. so it shouldn't stain a toilet.

i want 2 try it

fcgadget (author)2010-03-08

Simplest toilet trick...works better at night for women....

Blow up a large white ballon, place it in the toilet and close the seat and lid.

In the middle of the night when someone sleepily sits down,
    there's SOMETHING that touches them where NOTHING should be!

siasdo (author)2010-01-28

This one works at parties.  set a camera on a tripod in front of your toilet and record about 10 to 15 minutes of the toilet.  Just the toilet and nothing else.  Then, at the next party, wait for your victim to go into the bathroom to use the facilities, put your video in and play it for the crowd.  When the victim exits the bathroom and returns, they see everyone looking at the TV.  see how long it takes for them to realize the image is of the toilet where they were just doing their business.

camiecat16 (author)2009-09-29

i think it doesnt matter if it has already been done before....its all a good laugh anyway so why does it matter?

Huntman00 (author)camiecat162010-01-07

cause i wass going to do it at schoor so i would get in some big trouble

unominame (author)2009-09-26

have an idea get some vasoline or lard and cover the toilet seat and handle with it so when some one sits down they slide off and get an oily bottom

matthew178 (author)2009-08-07

LOLOLOLOLOLOL random, but swweeeeeet

me likey >:D great idea man. btw, could i come over to yours later lol? jk ><

scotchbrand (author)2008-05-18

best thing to do is heat up some clear jello and put into the bowl... about 2 ish cups of it... once done put a layer of water to give it the real look then if they pee or poop and try to flush they can't... so they have to get it out with there hands

THAT IS DISGUSTING...AND AN AWESOME IDEA. LOL

bigfootduck (author)scotchbrand2008-06-13

eww

da_h-bomb277 (author)bigfootduck2009-05-28

hilarious

MillenniumMan (author)2009-07-09

Here's one. Take a bendy-straw, cut the longer half til there's only two inches left before the elbow. Then, take the long end and stick it into one of the holes in the inner ring of the bowl where the water comes in to wash out the old crap. Bend the other half upwards at a 50 degree angle. Wait for the flush...... Well, if they didn't wet their pants before going to the bathroom, they did afterwards :)

Bartboy (author)2008-07-29

I remember when I was 9 at my grandparents house I messed with the "Innards" of the toilet, and made it spray water when you flushed it XD.
