Dangerous gasses? That really did not sound good at all. Now Hattie agreed with everyone that the bubble head charm was a good idea. But a lot of people had said that and she really did not want to sound like a broken record. So she was going to try and think of another spell that would be useful. Because there had to be more than one that would be useful.

Now. A bubble head charm would stop the gasses getting to you, but it would't really stop the object bringing the gases from getting to you. So that was where she was going to go from. "You could use the Depulso charm. So that you make the object fly away." Which would help with it not coming closer.
