Piranha 3DD

Piranha 3DD is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Piranha 3DD rather than just read about it. In short: Piranha 3DD is a 2012 American 3D horror comedy film directed by John Gulager and written by Marcus Dunstan and Patrick Melton. It is a sequel to the 2010 film Piranha 3D and the fifth installment in the Piranha film series, and stars Danielle Panabaker, Matt Bush, David Koechner, Chris Zylka, Katrina Bowden, Gary Busey, Christopher Lloyd, and David Hasselhoff.

Key takeaways

  • Piranha 3DD belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Piranha 3DD to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Piranha 3DD from memory before moving on to harder problems.

Reference excerpt

Piranha 3DD is a 2012 American 3D horror comedy film directed by John Gulager and written by Marcus Dunstan and Patrick Melton. It is a sequel to the 2010 film Piranha 3D and the fifth installment in the Piranha film series, and stars Danielle Panabaker, Matt Bush, David Koechner, Chris Zylka, Katrina Bowden, Gary Busey, Christopher Lloyd, and David Hasselhoff. The events of film take place after those of the previous film and include a school of bloodthirsty, prehistoric, carnivorous piranhas invading a newly opened water park in Arizona. Piranha 3DD was released in the United Kingdom on May 11, 2012, and in the United States on June 1, 2012, by Dimension Films. The film underperformed at the box office, grossing $8.5 million worldwide against a budget of $7.5 million. It received mostly negative reviews.

Plot A year after the massacre by prehistoric piranhas in Lake Victoria, Arizona, a massive eradication program has left the lake uninhabitable and the town largely abandoned. At Cross Lake, two farmers search the waters. Piranha eggs laid inside a dead cow hatch, and the farmers are killed and eaten. Maddy, a marine biology student, returns home for the summer to the water park she co-owns and is annoyed to find that the other owner, her stepfather Chet, plans to add an adult-themed section to the water park that allows nudity. Later that night, Maddy's friend Shelby and her boyfriend Josh go skinny-dipping in the lake, where a piranha fry enters Shelby's vagina. Their friends Ashley and Travis begin to have sex in their van, but Ashley accidentally releases the parking brake, causing the van to roll into the lake. Handcuffed to the van during foreplay and unable to escape, Travis is devoured by piranhas while Ashley, on the roof, calls for help. No one is around to rescue her. The van sinks into the lake and the piranhas eat her. The next day, the van is dragged out of the lake, where it is found to be empty. Kyle relays this to Shelby, who attempts to call Ashley, only for the call to go straight to voicemail. A distraught Shelby runs off, with Maddy following after her. Maddy finds Shelby sitting on a jetty, and goes on to console Shelby about their missing friends. While they are sitting on the jetty, they are both attacked by a school of piranhas. They manage to kill one, and Maddy, Kyle (a cop and Maddy's ex) and Maddy's coworker Barry take it to marine expert Carl Goodman to examine. He informs them that the piranhas may be moving between lakes and could evolve to travel over land. The trio returns to the lake, where they establish that the piranhas cannot enter the pipes connecting the lake and the water park. While Shelby and Josh are having sex, the piranha in Shelby's vagina bites Josh's penis, forcing him to chop it off. Both are hospitalized but survive. Kyle is revealed to be corrupt and taking bribes from Chet, who is pumping water from an underground river into the water park. Chet orders Kyle to keep Maddy from finding out about his plans. The adult water park opens with David Hasselhoff in attendance as a celebrity guest. Among the guests are Deputy Fallon and former cameraman Andrew Cunningham, survivors of the previous year's piranha attacks in which Fallon lost his legs. Fallon is there in the hope of overcoming his fear of the water. Maddy attempts to shut the water park down but is stopped by Chet and Kyle. The piranhas enter the area through the pipes and attack, killing many guests. Fallon uses a shotgun leg prosthesis to fight the piranhas, while Hasselhoff rescues a young boy named David. An uncaring Chet attempts to escape, but a low-hanging pendant banner decapitates him. Maddy instructs Barry to begin draining the pools while she attempts to save those still in the water. However, while rescuing people, she becomes caught in the suction and is dragged down to the bottom of the pool. Barry sees a dolphin-sized adult piranha swimming toward her and throws a litter trident to kill it. After Kyle refuses to save her because of his fear of piranhas, Barry, despite being unable to swim, leaps down and brings her to the surface, at which point Maddy is revived. Thankful to him for saving her, she shares a kiss with Barry, who reveals that he has a crush on her. Another employee, Big Dave, pours chlorine into the pipes, followed by a lit joint. A resulting explosion kills most of the piranhas. Kyle is also killed by a falling trident. The celebrations are cut short when Maddy receives a phone call from Mr. Goodman, who informs them that the piranha left with him has escaped its tank and can now move on land, to which Maddy replies that she already knows. A lone piranha emerges from the pool and decapitates David while he tries to photograph it. The film ends with the survivors taking pictures of David's corpse with his hysterical mother covered in his blood, and Hasselhoff, overlooking the incident from his chair, calls David a "little ginger Moron".

Worked examples

Example 1 — a first encounter with Piranha 3DD

Start with the simplest possible case. Write down what Piranha 3DD claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Piranha 3DD before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Piranha 3DD ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Piranha 3DD

In research
Piranha 3DD appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Piranha 3DD in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Piranha 3DD is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010s natural horror films, 2010s sex comedy films, 2012 3D films, so understanding it makes those chapters shorter.
In everyday life
Look for Piranha 3DD outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
