* According to [[Wizards' Ordinary Magic and Basic Aptitude Test|W.O.M.B.A.T.]], it may or may not be possible to turn an animal into a human. 
* Food cannot be created, but this is what [[Minerva McGonagall]] seems to do in ''[[Harry Potter and the Chamber of Secrets]]''. However, it is most likely that she used a spell that can summon food from one place to another without travelling through the middling space. This may resemble the charm or spell used by the Hogwarts house-elves, which transfers food from one plate in the kitchens to its counterpart above in the [[Great Hall]]. [[Molly Weasley]] also appears to create a creamy sauce into a pan in ''[[Harry Potter and the Goblet of Fire]]''. However, Gamp's law announces that you cannot create new food out of nothing, but you can conjure it if you know where it is. You can also increase the amount or quantity of food, which is what [[Harry Potter]] does in ''[[Harry Potter and the Half-Blood Prince]]'' when he performs a [[Refilling Charm]] on several bottles of wine.

* Food cannot be created; but since animals can be conjured (such as birds, using the ''[[Avis]]'' spell; snakes, using the ''[[Serpensortia]]'' spell; or buffaloes, as [[Filius Flitwick]], in ''[[Harry Potter and the Philosopher's Stone]]'', cites [[Baruffio]] as having done by accident) or transfigured (such as when McGonagall transformed her desk into a pig), one may theoretically take meat from the animal, which would supposedly allow the [indirect] conjuration of food. However, there may be some unforeseen side-effect of attempting this which preserves this rule (for example, nothing conjured ever lasts so the food and its constituents "conjured" in this way would disappear soon enough, preserving the rule).

===Possible Principal Exceptions===
 
 
''[[List of Harry Potter unofficial guidebooks#Guides, Folklore, Mythology|The Complete Idiot's Guide To The World Of Harry Potter]] speculates on the following four possible exceptions to Gamp's Law.''<ref>http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/20110711/LETTERS/110719997</ref>
 
 
Other possible candidates for the four remaining principal exceptions proposed are: love, (pre-existing) life, information and precious metals with the reasoning for each explained below.
 
*'''[[Love]]''' - known to be impossible to simply create in the Harry Potter universe, it can only be simulated through a [[Love Potion]], [[Entrancing Enchantments]] or the [[Imperius Curse]]. Even in these cases, the best one can hope for is obsessive infatuation, which fades when the spell or potion fades.<ref name="HBP">''[[Harry Potter and the Half-Blood Prince]]''</ref>
 
*'''Life''' - while it is shown throughout the series that '''new''' life'' can'' be created (e.g. birds produced using with ''[[Avis]]''<ref name="HBP"/> and flowers with ''[[Orchideous]]'') it is also firmly known that life which has already ended is impossible to be restored (which would include via conjuration).<ref>''[[Harry Potter and the Goblet of Fire]]''</ref> Hence, pre-existing life is impossible to conjure and therefore may be one of the exceptions to Gamp's Law. Interestingly, though, pre-existing life - like food - can also be multiplied ([[Engorgement Charm|in size]], at least) and summoned (such as with the [[Resurrection Stone]]).
 
*'''Information''' - a logical assumption, or else one would assume that many things that were seen as impossible in the series would be achievable; for example, students might conjure all necessary information before a test or [[Aurors]] might conjure information pertaining to the whereabouts of a wanted criminal (like [[Voldemort]] or [[Sirius Black]])
 
*'''Precious Metals''' - if [[wizards]] were able to conjure precious metals and therefore money then their economy would collapse or at the very least there would be no impoverished wizarding families (like the Weasleys), however, this is clearly not the case. Though one might counter this with the fact that [[J. K. Rowling]] once said "There is legislation about what you can conjure and what you can't"<ref>http://www.accio-quote.org/articles/2000/0700-swns-alfie.htm</ref> and that money may therefore be one of these substances whose creation is illegal, this does not seem to be the case, which leads one to think it was never banned because it cannot be achieved. For example, if the creation of gold was banned then one would expect [[Nicolas Flamel]] to have been arrested long ago, yet he never was. The [[Philosopher's Stone]]<ref>''[[Harry Potter and the Philosopher's Stone]]''</ref> is also reminiscent of the exception to the rule relating to food in that it only '''transforms''' other metals into gold but cannot create it (like how food can be transformed but not created). Likewise, [[Leprechaun]]s may create objects that look like gold or money, but which will, in time, change back to dead leaves or dirt; it is merely an illusion or transfiguration (once again similar to the allowance of transformation but not creation). Similarly, the [[Geminio]] Curse allows one to multiply (but not conjure from nothing) the desired object (in this case something made from gold), as was witnessed in the [[Lestrange Vault]] at [[Gringotts Wizarding Bank|Gringotts]] in [[1998]], which reminds one of the exception to the food rule allowing multiplication but not outright creation.
 
*'''Money and Shelter''': This is two items, but they are often inextricably linked: one can’t have a beautiful or large home without having money to pay for it. Although an interior of a room or area can be expanded, as the Weasleys did while camping at the [[Quidditch World Cup]] and while riding ministry-borrowed cars, and valuable objects can be multiplied, if the intention is to suffocate a thief inside a vault at Gringotts, they can’t be created from scratch.
 
*'''Clothing''': Even [[wizards]] of great skill—[[Remus Lupin]] and [[Molly Weasley]] included—cannot seem to conjure up new robes and are instead stuck with old, patched ones, ones that are too short, or ones that are hopelessly out of style. If clothing were not one of the exceptions, Lupin would have long ago conjured a new wardrobe, and Ron would have avoided his dress-robe embarrassment at the [[Yule Ball]].
 
*'''Body Part Removed by [[Dark Arts]]''': In the [[Wizardkind|wizarding world]], all sorts of body parts can be repaired and even conjured from scratch (like the regrowing of Harry’s bones after his quidditch accident in the [[Chamber of Secrets]].) But these same body parts—and the entire body, in the case of the [[Killing Curse]]—cannot be replaced or repaired if [[Dark Arts]] was involved, no matter how skilled the healer.
 
*'''Temperature''': The conjuring of heat or cold or the transfiguring of something warm into something cold (and vice versa). Although [[wizards]] can produce water ([[Aguamenti]]!) and can emit steam from their wands through the hot-air charm—steam that lightly melts objects like snow or dries objects like sopping-wet clothing—wizards cannot raise or lower the temperature of the air, stop rain or snow from falling, slow or speed the wind, or heat or cool large bodies of water.

Hermione: "Your mother can’t produce food out of thin air, no one can. Food is the first of the five Principal Exceptions to Gamp’s Law of Elemental Transfigura—"
Ron: "Oh, speak English, can’t you?"
Hermione: "It’s impossible to make good food out of nothing! You can Summon it if you know where it is, you can transform it, you can increase the quantity if you’ve already got some..."
Hermione Granger and Ron Weasley on the exceptions to Gamp's Law[src]

Gamp's Law of Elemental Transfiguration is a law governing the magical world. There are five Principal Exceptions to Gamp's Law, one of which is food.

It should be noted that while food cannot be outright created from nothing, it can be multiplied if one already has some food to multiply, it can be enlarged or the food can be summoned if one knows the approximate location and is fairly sure the food will still be there.[1]

History

In September 1997, after Ron commented that his mother could make good food out of thin air, Hermione stated that this was impossible, as food is one of the five Principle Exemptions to this law, but this only irritated Ron, who wanted her to "speak English", but was not satisfied by her explanation.[2]

On 1 May, 1998, after Neville Longbottom noted that the one thing that the Room of Requirement did not seem to be able to provide was food, Ron commented that food was one of the five Principle Exceptions to this law, to "general astonishment".[3]

Behind the scenes

  • Gamp's Law apparently uses the surname of the person who discovered it. Hesper Gamp, a witch married to Sirius Black II, might be that person or a relative of that person.[4]
  • According to W.O.M.B.A.T., it may or may not be possible to turn an animal into a human. 
  • Although many things appear impossible to conjure, there is legislation in the wizarding world about what can and cannot be conjured.[5] 
  •  In chapter five, "Weasley's Wizarding Wheezes", of Harry Potter and the Goblet of Fire, Mrs. Weasley creates sauce without an incantation. Quote from American paperback edition: "A creamy sauce poured from the wand tip as she stirred."
