History Main / ChanceActivation

* In ''WesternAnimation/TheBatmanVsDracula'', The Penguin just ''happens'' to cut his hand on his umbrella-sword, giving Dracula the drop of blood he needs to rise from the grave.
* In ''WesternAnimation/AladdinAndTheKingOfThieves'', Razoul the guard tries to break into the stronghold of the Forty Thieves, but he can't remember the password. After repeated failures ("Open -- ''carraway!''"), he leaves in disgust, only for one of his guards to offhandedly comment, "I thought he said it was 'OpenSesame'?"

* In the ''Film/GreenLantern2011'' movie, Hal has been given a magic ring and a magic lantern by the dying Abin Sur, but no instructions on how to use either, nor what the Green Lantern oath is supposed to be. He fools around with both for the better part of an afternoon, offering a number of possible activation phrases (including [[WesternAnimation/HeManAndTheMastersOfTheUniverse1983 "By the power of Greyskull!"]] and [[Franchise/ToyStory "To infinity and beyond!"]]) until he gets the connection ''just so'' and the ring and lantern take over for him.
* Seen in ''Film/TheCabinInTheWoods'', and exaggerated: the five teenagers go into the cellar, and ''each one'' starts fiddling with a different mysterious object (necklace, music box, puzzle sphere) -- and only when one girl reads aloud from a book does she "Activate" it. On the other side of the screen, the organizers of the scenario resolve their betting pool on which monster was going to be summoned.
* In ''Film/SexMission'', the password for the emergency exit to surface is, essentially, "fuck!" (in original Polish, "kurwa mać!"). The hapless protagonists only shout the word out of frustration.

* In ''Literature/DeltoraQuest'', Lief doesn't realize that the Belt of Deltora has to be activated at all - and then realizes that the stones need to be in a very specific order. The Belt had been working at minimal strength until he figures that out.
* ''Literature/CiaphasCain'': In keeping with their usual track record of messing with Necron artifacts (several balls in a large slotted slab, producing different effects depending on number and position of balls), the Adeptus Mechanicus manages to summon a daemon, which Cain is fortunately able to take out rapidly.
* In ''Literature/TheMysteriousBenedictSociety'', the protagonists discover the outline of a secret door in a boulder, but are unable to figure out how to open it. Finally Sticky kicks the rock in frustration, and the door swings open. The kids realize it's set up that way because Mr. Curtain likes to ram doors with his wheelchair.

* In one episode of ''WesternAnimation/TheSimpsons'', after much [[HilarityEnsues hilarity ensuing]], Homer drops a priceless Egyptian artifact, which is then discovered to be a music box which nobody knew about. Lisa decides that it's best to keep it just between them.

* In Literature/DeltoraQuest Lief doesn't realize that the Belt of Deltora has to be activated at all - and then realizes that the stones need to be in a very specific order. The Belt had been working at minimal strength until he figures that out.

A group has found an [[PlotDevice item]] (an artifact, some piece of supposedly incomprehensible technology, etc.). The group, most likely including the [[TheSmartGuy smart guy]], starts discussing how it will take quite a bit of time and research to discover the item's purpose and/or how to use it. Meanwhile, another person in the group (often TheHero, but not necessarily) is fiddling around with the item, and unlocks/activates/arms/whatevers the device, interrupting and possibly upsetting the others in the group.

Often accompanied by an ActivationSequence.

* ''ComicBook/WonderWoman1942'': Etta and ComicBook/SteveTrevor are discussing how impossible it's going to be to get a spacecraft they're in to do anything and Etta manages to launch them both into space by plugging in two wires and pulling a lever. Neither are pleased since it was accidental, the government is probably going to charge them with theft and they still have no clue how to actually control it.

* In the Literature/{{Discworld}} book ''Discworld/{{Thud}}'', [[spoiler:It's revealed that this is how MadArtist Methodia Rascal activated (and was subsequently driven even crazier by) the dwarfs' talking Cube. As he [[ItMakesSenseInContext thought he was a chicken]], the noises he would make (Awk! Awk!) happened to sound like the Dwarfish word that turned it on.]]

* Occurs in ''Disney/TreasurePlanet'', after the Benbow Inn has been burnt down and the Hawkinses are staying with [[TheSmartGuy Dr. Doppler]]. The good doctor is explaining that he has no clue of function of the [[PlotDevice "odd little sphere"]] which Jim now possesses. Cue Jim fiddling around with the sphere and unlocking it, thereby discovering its function; a map containing the location of the legendary Treasure Planet.

* In ''Disney/AladdinAndTheKingOfThieves'', Razoul the guard tries to break into the stronghold of the Forty Thieves, but he can't remember the password. After repeated failures ("Open -- ''carraway!''"), he leaves in disgust, only for one of his guards to offhandedly comment, "I thought he said it was 'OpenSesame'?"

Compare ShaggySearchTechnique, where the person or group is actively trying to solve whatever puzzle is present, inadvertently finding a solution through dumb luck. The main difference between these tropes is a matter of intent; Shaggy searches begin intentionally, while a chance activation is just someone fiddling with a PlotDevice and it "working".

* The Air element stone in ''Film/TheFifthElement'' is opened by pure dumb luck (some dude sighing at it in frustration), providing the key clue needed to open the three others.

* ''CiaphasCain'': In keeping with their usual track record of messing with Necron artifacts (several balls in a large slotted slab, producing different effects depending on number and position of balls), the Adeptus Mechanicus manages to summon a daemon, which Cain is fortunately able to take out rapidly..

* In the first episode of {{Black Books}} Fran mistakenly buys a large spherical object with a teapot-like spout to sell in her curio shop. She spends most of the episode obsessed with discerning the object's purpose. In the final seconds of the show Bernard pats his pockets, looking for a light for his cigarette. Without thinking, Manny picks up the strange object and squeezes it, producing a flame from the spout which he lights Bernard's cigarette with. Fran lets out an exasperated scream.
