Alice coughed until she was sure just about all the mud had gotten out of her mouth. She pointed her wand into her mouth and muttered, "Aguamenti," a small stream of water entering her mouth and cleaning out the mud she couldn't get out by sheer spit.

Once she was done she pointed the wand at the top of her head, the water sending the mud streaming down her robes and back into the mud pile. Once Alice was pretty sure she had gotten most of the mud out of her hair she grabbed the mop (which had so kindly flown down and was now in a heap next to her) with her left hand and mounted it.

Alice was not going to go quite as high this time...one trip into the mud puddle per flying class was plenty for her.
