I've been looking for the posts on Drooble's Best blowing gum and 
haven't been able to find any mention of something that's been 
bothering me...

I recently read in one of the first three HP books (I cant remember 
which, but I think it was PoA) that Drooble's gum "filled a room with 
blue bubbles that refused to pop for days" (or something similar).
 
Now, if the Longbottoms (or, specifically, Alice) have been chewing 
Drooble's in the hospital , wouldn't there be bubbles all over the 
place? Wouldn't the staff have tried to prevent her from chewing it 
to avoid having to clean them up?
