Vigroids

Vigroids 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 Vigroids rather than just read about it. In short: Vigroids (also Mighty Imps, formerly Nigroids) was a brand of liquorice sweet. The small black pellets were particularly marketed as an expectorant lozenge for singers, using the slogan "for clarity of voice".

Key takeaways

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

Reference excerpt

Vigroids (also Mighty Imps, formerly Nigroids) was a brand of liquorice sweet. The small black pellets were particularly marketed as an expectorant lozenge for singers, using the slogan "for clarity of voice". The Nigroids/Vigroids brand was acquired by Ernest Jackson & Company Ltd of Crediton, Devon, England, in 1974. After several changes of ownership, Ernest Jackson became a subsidiary of Kraft Foods in 2011, and later of Mondelez International. The principal ingredient of Vigroids is liquorice block juice. The company warns that liquorice can raise blood pressure, and that those with a history of hypertension should not take too many. They suggest limiting consumption to 10 per day. No sugar is used. Small quantities of other flavourings such as menthol, eucalyptus and peppermint are added to help the pellets act as a breath mint.

History

Nigroids were invented by Ferris & Co. Ltd., manufacturing chemists of Bristol, England, in 1900. The company promoted them with the slogan:

For Hoarseness, "Tickling of the Throat," etc. They afford protection to the Voice, Throat, and Chest, against ill-effects of fog, cold and damp. Invaluable to singers and speakers. Ernest Jackson acquired the brand in 1974. In 2010 the name was changed from "Nigroids" to "Vigroids". Vigroids/Mighty Imps were listed on the Ernest Jackson Web site until October 2014, but no longer appeared from January 2015.

Worked examples

Example 1 — a first encounter with Vigroids

Start with the simplest possible case. Write down what Vigroids 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 Vigroids 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 Vigroids 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 Vigroids

In research: Vigroids 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 Vigroids 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: Vigroids is common in secondary-school and first-year university syllabi. It links to neighbouring topics Brand name confectionery, Breath mints, British brands, so understanding it makes those chapters shorter.
In everyday life: Look for Vigroids 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.

Frequently asked questions

What is Vigroids in simple terms?

Why does Vigroids matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Vigroids?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
