Well, it does say, "Drink Me", but that doesn't mean you have to drink it. [Oh Jasmine, you have no idea who you're talking to.]

But they seem to be different for all of us. I've heard the colours determine what kind of powers, but even then you don't really know until you've tried. Mine, for instance, is gold, which means it should turn me into an animal... but I haven't tried yet, so I haven't a clue what kind of animal.

So if you drank it, then yes, you do have magic. Though you seem rather extraordinary to me just the same, Alice.
