章節 94: Chapter 94
The professor walked down the aisle.
"Welcome to transfiguration. The magic of transforming objects into alternate forms. You will soon be shocked to discover that in the next five years, you will only learn five actual spells in this class." The old witch paused and walked back up to the front of the lecture room.
A few of her classmates did indeed look surprised. Not her, of course.
"This is because one spell will cover almost all our efforts up until your NEWTs." McGonagall pointed her wand at a goblet on the desk in front her. It turned into a small statue of a knight on horseback. Another wave of her wand turned it back. She then picked up the goblet and pointed her wand at the table itself. The desk turned into a pig.
"I just used the same spell on both the goblet and the desk, the general transfiguration spell." McGonagall said, turning the pig back into a desk again. "This is the spell we shall spend the majority of our time with." You may well be able to cast the spell by the end of this class. But to master it, will take a lifetime."
She diligently wrote down, 'Point 1. General transfiguration spell - lifetime to master.'
"To cast the general transfiguration spell we channel our ready magic through our wands with intent to affect the change."
McGonagall picked up a stick of chalk and wrote — A SPELL IS READY MAGIC WITH INTENT. "This applies to all magic, not just transfiguration. When you cast a charm, or a jinx, you are doing the same thing. Of course, for the spell to work, magic has to also agree with your intent, and that often requires additional actions. Hence, magic words, wand motions, rituals, etc."
She copied this down too. She already knew it, but that was beside the point. Good students wrote things down.
"When we cast the transfiguration spell on an object, we channel the spell into the object. The object will continue to change as the intent channelled into the object changes." The professor wrote — A TRANSFIGURED OBJECT HOLDS THE SPELL WITHIN ITSELF.
"When the magic in the object reaches zero, the object reverts back to its original form."
McGonagall then reached under the desk and brought out two large glass bowls, a block of wood, and an hourglass.
"Class, please watch closely."
She leaned closer to get a better view.
McGonagall placed the block of wood in the first bowl, flipped the hourglass, and pointed her wand at the wood through the bowl's top. The wood turned into water.
"I have just channelled a tiny amount of magic into the wood."
The professor looked down at the bowl and glanced at the hourglass. Several seconds later the wood turned back into water. McGonagall tapped the hourglass — 5.09 seconds.
"This time, the transfiguration lasted five seconds. Now, watch what happens this time."
McGonagall turned the wood back into water, but this time, she poured half the water into the second bowl. The moment the water in the second bowl lost contact with the water in the first, it turned back into wood, a block, just like it had been before, but half the size. The first bowl, though, still contained water. They waited. They waited some more.
The water turned back into wood. McGonagall tapped the recently re-flipped hourglass — 9.65 seconds.
"Can anyone tell me what just happened?"
Her hand could not have moved faster.
"Yes, Miss Granger?"
"Once you poured half the water into the second bowl, it lost contact to the spell, so it turned back into wood. The first half then had only half as much mass to keep transfigured, but the same amount of magic, so it stayed transfigured twice as long."
"Well done, Miss Granger. Two points to Slytherin."
She beamed.
McGonagall wrote on the board TRANSFIGURED OBJECTS USE UP THE MAGIC IN THEIR SPELL UNTIL THERE IS NO MAGIC LEFT.
The professor transfigured the wood into water again and then held the bowl up high so their attention was focused on it. Her voice was loud and sharp. "If you were to take a sip of this, you would end up with a mouth full of wood or sawdust. If you were able to drink this, all in one go, without the contact being lost between the liquid stream, you would end up with a stomach full of transfigured water. This would be a very bad thing. The water would gradually turn back into wood as individual molecules were absorbed by your stomach. This would cause severe damage to your stomach lining. You should never drink or eat anything that has been transfigured. Ever.
She grimaced. Harry had described some of the more graphic results that could be achieved with transfiguration if you were really trying hard enough. Just thinking about them made her squirm. The class seemed to have the same idea. One Hufflepuff girl in particular didn't look well.
McGonagall put the bowl down on the table. "If we kept this transfiguration active for long enough, we would start to see a thin film forming on the top of the water — wood dust from the water molecules that evaporated from the water and lost their transfiguration."
Under the last blackboard line, McGonagall wrote — IF YOU ARE UNCERTAIN IF SOMETHING YOU ARE ABOUT TO EAT OR DRINK CONTAINS MAGIC, CHECK FIRST! "After the general transfiguration spell, we will learn the spell that checks an object for the presence of magic. If the object contains magic do not consume it."
A tentative hand was raised towards the front.
"Yes, Miss Roper?" "What about those chocolate frog things? They contain magic don't they?" Several rows down, she heard Malfoy mutter, "stupid mudblood."
Her eyes narrowed.
Professor McGonagall paused. "Yes, they contain animation magic. However, they are sealed in special packages to prevent tampering. So long as you have just opened one, it should be safe to eat. But if you are still uncertain, there are more advanced spells to determine the exact nature of the magic an object contains. We will not be learning them until much later though."
She swept from the blackboard to stand in front of the desks.
"Now, I am going to hand each of you an iron nail, and you are going to attempt to turn it into a small wooden spoon, like so." A nail turned into a tiny wooden spoon.
