Shake n' Vac

Shake n' Vac 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 Shake n' Vac rather than just read about it. In short: Glade Shake n' Vac is a powdered carpet freshener. The powder is shaken onto the carpet before vacuuming.

Key takeaways

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

Reference excerpt

Glade Shake n' Vac is a powdered carpet freshener. The powder is shaken onto the carpet before vacuuming. It is marketed and sold in the United Kingdom by S. C. Johnson & Son. First sold in 1979, the product's "Dancing Woman" television commercial during the 1980s was voted one of the most popular in Britain.

Advertising First going on air in the early 1980s, the advertisement featured the English actress Jenny Logan, dancing about in a typical British living room in high heels, shaking the powder onto a carpet and vacuuming it up, while appearing to sing a musical jingle. The main lyric is "do the Shake n' Vac, and put the freshness back". The commercial was produced by Benton and Bowles advertising agency, written and art directed by Peter West and Guy Winston and produced by Simon Wells. Although the Shake n' Vac product was on sale in shops in 1979, ITV industrial action of 1979 resulted in the television advert being delayed until 1980. The jingle was in a 1950s rock and roll retro style. In 2000, the advertisement polled 18th place in the Channel 4 The 100 Greatest TV Adverts programme, and an ITV list in 2005.

Worked examples

Example 1 — a first encounter with Shake n' Vac

Start with the simplest possible case. Write down what Shake n' Vac 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 Shake n' Vac 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 Shake n' Vac 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 Shake n' Vac

In research: Shake n' Vac 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 Shake n' Vac 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: Shake n' Vac is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980s television advertisements, Advertising campaigns, American television advertisements, so understanding it makes those chapters shorter.
In everyday life: Look for Shake n' Vac 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.
