Alexandrie walked into the classroom and read the board and thought about the problem before grabbing her wand, what was that one spell again the one to cause an item to be hidden.. Hmm.. well one could be vanished but that had already been thought of no doubt so so getting rid of both cookies.. hmm.. she couldn't think of something else so "Evanesco." Alex whispered carefully vanishing one of the cookies and grabbed the last and hid it one of her note books she never used and slid the note book into her big bag that unless the Professor could see through objects wouldn't be able to see it. She put her wand away behind her ear like normal waiting for the Professor to show up.
