Oh wow, was it because they were outdoors? A lot of oxygen must have been going to their heads tonight because her class seemed to be on point..even numb nut Shacklebolt who had almost managed to spoil the evening gave a good answer.

"Very good class, take three points each and umm..Mr.Odessa can take five for the insightful demonstration. Moving on.." She reach down for a small cup and tapped it, performing the charm non verbally. She then placed the cup down in front of them and started pulling cushions and chairs and all kind of assorted objects from her tent, which she then dropped into the cup.

"So like Mr.Odessa and the rest of you pointed out. It changes the internal dimension of the object while the outward appearance remains the same." The cup wasn't looking any different even with everything stuffed into it.

"We'll be attempting this charm on the tents you are sitting in front of." She flicked her wand at the fire and then in mid air she wrote out Magnus Centrum in flaming letters. "This is the incantation...and the wand movement is a light tap on the object you are placing the charm on." She stepped out of the way of her tent."Everyone come forward and get a cup and a cushion..if you successfully perform the charm on the cup and you're able to fit a cushion in we'll move on to the tents. If you have any questions relating to the charm, please do not hesitate to ask me."

"Oh and Mr.Shacklebolt..you may come and collect a cup as well and cushion as well."
