So anyone with the invisibility cloak (The Deathly Hallows cloak) can hide themselves, almost completely.
Can this effect work on inanimate objects in any capacity?
As someone in the comments said, his cloak hides his clothes while he is wearing them. Does this extend to any more objects he is holding? Even if they are luminous? For example, he had a lantern when he was searching the restricted section of the library, and he put it out and put it under his cloak. Is the invisibility cloak nullified by bright objects?
And does it work on non-sapient creatures? e.g. Skrewts, griffins, etc.
