Hugo looked at the cookies. He knew one way, but then they would re-appear in the loo a day later. How could I make a cookie dissapear? He looked around, helpless.

He flicked through the pages of his charms book, came across a spell and said Depulso, but failed. The book stated that fourth-years can only learn this spell. Great.

He looked in his book and got out his wand again. He whispered Reducto to it. The cookie burst in pieces. Awesome. Now what to do with the other one?
