Aurora nodded, concentrating. Wooo! Her potion was burgundy!!

She took her wand and, pointing it in the centre of her cauldron, drew a spiral upwards saying, confidently, "Agitatem." Then, as quickly as she dared, cast a Glacius spell to put out the fire under her cauldron and cool it. Oh please, please, pleaseeeee let that be fast enough. Well, the potion was still moving... hopefully that was correct...
