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!!! :)
#2 is hilarious!
lol i like number 2
omfg! there all hil.arious

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)
or red, its hilarious if you use red
Pigs blood? From the butchers. It would smell awful also... I think.

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
Wesley6663 years ago
Do a double decker. Poop in the tank, surprise when the next person flushes...

nice one

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.
Huntman004 years ago
if u put food coloring in the tank so when they flush it will turn that color..........will it stain the bowl
 it shouldn't if it's just food colouring.
ur shure??
 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.
LOLOLOLOLOLOLOLOLOL
i want 2 try it

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!

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.

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

unominame5 years ago
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
matthew1785 years ago
pretty good kind of bad
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.
LOLOLOLOLOLOL random, but swweeeeeet
me likey >:D great idea man. btw, could i come over to yours later lol? jk ><
scotchbrand6 years ago
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
eww
hilarious
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 :)

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.
you do that by taking off the top finding the hose and then doing this. there will be two things the hose is attatched to a water tower looking thingy and a piece of pvc sort of pipe you need to remove it from the pvc pipe and then place it on the outside of the toilet by the handle and put the lid back on. don't prank yourself,
grandparents house? e-vil! hahha

Like Dr_Stupid said, this has been around forever. If you don't check for this on April 1st, you almost deserve what ever you get :P
Here is one. 1. fold two ketchup packs and place under the bumps on the toilet lid. 2. watch when somebody sits down and has ketchup sprayed all over the. 3. run
animal03076 years ago
OK thats funny... but my friends and I came up with that one about 2 years ago...and we actually pulled it off in a walmart bathroom... unfortunately we didn't get to see what happened
welcome to 2 decades ago...we were doing this one in the late 70's in 2nd grade. It amuses me how you kids think this "sh*t" is new.

No, but people should really learn to do their research and find out if what they think is something "Hey I thought of this" instead of "This has been done before, and here are its origins, but I'm going to show you how to do it today"... This is all part of learning. I can't begin to describe the number of things that I thought I thought of....but after doing a little looking around, it's been done before. If you live by the rule: "Simpsons did it"....in almost everything, you'll save yourself a lot of grief.
Was that called for?
Really, Cool!

shishnit6 years ago
I don't get how this would work, when you pee you lift up the seat, thus exposing obvious duct tape....?
not in public bathrooms XD
You're supposed to, I hate the people who piss all over the toilet seats, makes it really difficult to take a number 2.
i tryed it on my sister LOL LOL LOL LOL LOL LOL
take all the light bulbs out of the bathroom and leave the seat up, that ones for the ladies, although i wouldnt do that to my girlfriend unless she did something really bad to me.

You could connect the tubes from the back of the loo and rig it so there is piping running up the back, and then curve it to the front. When you pee, it shoots back at you

This Prank is GRRRRRRRRREAT! lol
joechump6 years ago
We did this once in halls at university. Unfortunately the person who we got was called Psycho Jim (an angry chap!) He cornered me in the lift the next day and asked who had done it! I told him it was probably the lads from the floor above! Don't remember being so organised as to have taped it down. Cling film is pretty clingy anyway. Great trick. Only problem is, you're not there to see their face!
Redgerr6 years ago
thats cruel, lol funny if they had to go to the batheroom the other way :O better lookout next time :O lol
WOW! Freaking hilarious idea. I definitely want to do this... at school. ;-) GREAT JOB! +1 rating.
I think don't think schools have tanks for their toilets. Probably for reasons like this.. I mean, you're in a closed space with nobody there.. no way to tamper-proof it... I'm not sure, of course, but I've never seen a toilet with a tank outside of a home.
ya, my school has them 10 feet off the ground. It WOULD be great if wee could reach them.
I can!
Thanks for the comment!
Thats going to be sweet!! :] If you do do the prank at school, see if you can manage to take pictures or record a video!
firemt6 years ago
the best one I found is most ppl have plungers in the bathroom add a little vasaline to the rim of the plunger place the plunger over the drain hole and pump it a few times then flush creates a wonderful vacuum and it a real pain to get out you have to stick something in and break the seal.
yay im in your instructable!
stimky6666 years ago
This would be better to do on the ceramic/plastic part, that way if it's a guy that lifts the seat, he'll still make a mess everywhere.
Rishnai6 years ago
Not really something to do to the toilet itself, but hilarious to do: Wait in a stall, and when someone sits down in another stall, say hello, then launch into trying to convert them to a religion--real or one you just invented. Or ask if they own a microwave, then start explaining why anything that gets that hot without fire is from the devil... at least until they hurry up and leave.
Esmagamus6 years ago
Well, you can always disconnect the pipe in the back of the toilet and wait to see 10 liters of water flowing out of the stall as someone runs out of there.
Derin6 years ago
when you are in stalls wait till they go in beside you and throw a wireless cam at them ps connect cam to the public tv
I3uckwheat6 years ago
Try putting lobsters in the tank and untie there claws so when the next person sits OUCH!
Bartboy6 years ago
I just got a great idea! you get fish aquarium tubing and extend the little pipe on the flusher so that you can aim it better!
Bartboy6 years ago
I love the fact that you include other peoples ideas in this instructable . Hint Hint.
Bartboy6 years ago
also . you could attach a water balloon to the little pipe hose and have it fill up, if they try to take it off water will go everywhere, if they don't Ka-ploosh!

Baking soda in the bowl, and vinegar in the tank. When they flush, it produces CO2 and overflows.
It works even better if you put some dishwashing soap in the tank with the vinegar. Then when it makes CO2 it captures all of the gas. ;)
LOL. wow also if you upperduct (pooping in the back of the toilet) thats sorta a grows thing lol.
Upper-Decking is boring and overdone. It's expected at least once a year. It happened once at work and I had to go tank fishing. :(
eww. ok so thats what its called my oldest brother called it upperducting a toilet. well you can also put a hole box of dish soap in lol.
Think of this: "How would I clean up this God-Awful mess?" That usually stops pranks from going too far.
well you don't the next person dose. lol and I'm not that kind of person the worst prank I ever pulled was a fake poop made out of mud and put it in the entrance of a bath room. Lol once I made a fake spider (as big as a CD) on a string come down off a fan blade on to my grandmas bed while she was standing next to the bed talking with my brother.
I'm so doing that.
Awsome!

If you don't like someone just put plaster of paris or ready mix cement in the tank. it will never flush again.
stinkymum6 years ago
What about the poor woman who will probably have to clean up the mess?
QwertyuioLP6 years ago
Bubble wrap under the seat sit and get scared!!!!!!
who's going to clean it up?
If 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.
Or you could pee in the tank. Highschool janitors hate me.
oh snap i did that twice people had to flush like 4times
solo.card6 years ago
I was going to post this prank, but I didn't think it fit with with the contest. Anyway, my research found that you don't need anything to stick down the film. If you pull it tight enough it will stay. Also, I work for the company in your avatar...
cool can you give me discounts?.. lol
Really Element! Sweet!! What do you do for them?
yeah "snap pops" under the seat yeah that would be sweat!
sweat or sweet? lol
oops sweet lol.

Heat shrink window film is a better choice. At this time of year it's $0.99 per box and comes with clear double sided sticky tape.

I Got one. Tape a scary halloween under the part that you open so that when somebody opens to go. they get SCARED out of thier mind
Aar000n3y6 years ago
I think it's a funny idea, but really, what kind of guy doesn't lift up the seat, and then after that, what guy wouldn't notice all of the light shining off the plastic wrap?
For one thing, every time I've done this to my friends it has worked (3 times). So, it might work it might not.

add this: Get gelatin and boiling water, Mix it together real good, Put in toilet and stir with brush! You have to scoop out your poo!!!

ah, this prank i always wanted to yoused but my parents would KILL me
inquisitive6 years ago
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!
Thats really cool!!!
Dr.Paj6 years ago
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.
Domindude36 years ago
It's a good idea, but you should do is do it in a public bathroom, and wait in the next stall for someone to go. The only problem I can see is that if you look closely yuo can see the wrap. Still like the idea though.
Not the newest idea on the market, but an out-and-out classic in my book. Very nice.
I agree!

and who has to clean up the mess????? the water level in your toilet bowl is on the high side you may have a bloakage
Just take a good laugh and you and the victim (or just the victim) clean up the mess.

another different way to do this that is less noticeable is dumping some gelatin in it. That way it works if they pee as well.
