How to Enter the April Fools Contest




Good-natured pranks, tricks, shenanigans, and more are all welcome on April Fools' Day!

We want to see what clever tricks you have up your sleeve, so we're having an April Fools Contest! Show us how you do your own prank and you could win some cool prizes! Just make sure it's all in good, clean fun - no dangerous or mean-spirited pranks, please.

This is a short contest, but it will end a few days after April Fools' Day. So if you want to keep your own prank a secret until after you've pulled it off, you have a few extra days to post it on Instructables.

We'll be giving away some cool books and t-shirts to the winners. Winners to be decided by a combination of user vote and Instructables judges. Full Instructables and slideshows will be eligible - just be sure to include enough information so someone else can repeat your work!

Now show us how sneaky you can be!

    Best one was played on me by my then 8 year old son. He knew my routine was to get up and make my coffee every morning just seconds after getting out of bed. I was basically walking in my sleep. I walked up to the sink and as I did every other morning turned the faucet on to fill the coffee pot. It was then when I realized I was being hosed down with ice cold water from the hand held sprayer that was pressed into the open position using a rubberband. You talk about a wake up call, holy s*@t, that woke me up. I heard him in his bedroom laughing his a$$ off. That was 17 years ago, and I still remember it every April fools, lolol......

    I thought of some nice April Fool's projects. 1. How to make a Faster than Light drive. 2. How to turn Lead into Gold. 3. A force field generator.

    No dangerous? Mmmmm, I am really sad XD I just wanted to write an Instructable of nitrogen-triiodide or nitrogen-tribromide. Unstable explosives but if you don't use much or you store it properly than there will be no problem and it is a good fun (not good fun for old people, for young kids and for people who have bad nerves).

    ...not exactly? Yes, all pranks rely on various forms of misdirection and/or deception, so it logically follows that when the mark finds out the truth, they suffer a minor blow to their dignity, which is often worsened if they were made to look foolish in front of their peers. This feeling of betrayal is common among all prank victims, though the degree that they express it depends on their personality and friendship (or lack thereof) with the source of mischief.

    "Mean-spirited", to me, carries the connotation that the prank has a destructive way of emotionally and/or physically denigrating the target without yielding justifiable comedic entertainment for everyone involved (more specifically, they should not suffer any bodily harm or extended psychological duress and be able to laugh with all involved).

    Ramming a potato into the exhaust pipe of someone's car with a broomstick is an example of a mean-spirited prank. Though there is great comedic potential, the reality of the aftermath is that the car will be rendered useless until the mark shells out cash for a mechanic to remove said potato.

    On the other hand, this peep prank is a wonderful example of proper mischief. Humor can be derived from the sheer astonishment of the mark when they open said egg, or steel themselves for a coating of yolk when you throw another such egg at them, only to find that they were never in danger to begin with.

    Somehow, I suddenly feel that my ulterior purpose for joining Instructables was to enter this contest with something novel for future mischief-makers to come. And with this remark, I shall begin planning my course of action to fulfill my destiny.

    Strange.... when we were at college, we were forever playing pranks on one another. No hurtful things were done, it was always related to things! We put a tree in some-ones room one night, all waited patiently for the occupant to return. He was slightly drunk, so he walked in, made a about turn, and tried to go into the room next door. We had a good laugh then we had to clean up, twenty guys did it in 5 min flat. No not all pranks are BAD!


    April Fools originated when the Catholic Church would mock local pagans for believing the first day of Spring to be the first day of the year. Anyone pranking me is getting punched for their insensitivity to the oppression caused by ideological imperialism.
