From the article:
- "While, according to Ollivander, any object can channel magic if the wizard is strong enough, wands are the most commonly used because of their efficiency (due to the owner's bond with the wand itself). This can explain how some wizards are able to use spells without wands (for example, retrieving an item with Accio)."
This is a misinterpretation of Ollivander's statement in Deathly Hallows that
- "If you are any wizard at all you will be able to channel your magic through almost any instrument."
This statement is made in the context of using another's wand, versus using one's own wand, and not whether or not you can channel magic through, say, a rock – so the word "instrument" should be taken to refer to wands specifically, not "things". Much as saying a talented musician could get a decent sound out of any instrument would suggest an actual musical instrument more than it would suggest a random pastry bought from the nearest bakery.
As stated by J.K. Rowling:
- "As established by Ollivander, a wizard can use almost any wand, it is simply that a wand that chooses him / her will work best."[1]
