Professor, is it true that there is a mental component to this spell? As well as the hand movement and verbal component? The spell caster must visualise either the resulting cleaned thing or the object he or she wishes to have vanished, when the spell is cast?
Transfiguration Class 1

Yes, it does require a mental component as you must have known that Harry Potter once made a glass vanish without actually performing the spell. So, it requires mental component more than the spell. And he made it come back with the conjuration spell which unvanishes things. He must see the thing he wishes to vanish and to unvanish or conjure he needs to needs to visualise it

Is this what you say to a Proffesor Miss Cloud. You do not say you love the class of a professor. You like it or not you must learn it. 3 points from Slytherin for disturbing the class.

Thank you, professor
Good morning everyone. I am Professor Rook and will be taking Transfiguration for you all. Today, that is our 1st class we will be learning a vanishing spell.
Incantation of the spell is Evanesco. Spell it ev-an-ES-ko. Repeat after me. Evanesco. *Students Evanesco* Good. Hand movement -
What is the effect? It simply vanishes objects. It vanishes both animate and inanimate objects into non-being which is to say everything. It is a important subject and will be asked at your OWLS. Invertebrates like snails can be rather simple but mammals like mouse are tough. The greatest challenge was a cat and our ex student Hermione Granger was the 1st to manage to do it in her mid-year. Ahh such an excellent student she was. And back to the subject- Certain objects could be enchanted to resist the spell, such as fireworks. Fred and George Weasley charmed their Weasleys' Wizard Wheezes fireworks so that anyone attempted to vanish them will fail but not only that but it had been multiplied by ten each time. Those cheeky b*stards. Okay that is all for today, any doubts shall be clarified and there will be a quiz session soon in the comments and 5 points per correct answer and 5 negative per wrong answer. If you do not answer 5 points shall be taken. Good day to you all. Enjoy your future sessions.
