Movie: Shock! Horror! NoTW HP magazine "not too bad"

[Vanessa]

The News of the World has been an object of ridicule for me, ever 
since I was ten and heard mark haywood's dad refer to it as the 'news 
of the Screws'.

But actually, they did OK with their pull-out section.
Whilst it is mostly a rehash of photos we've seen before, and their 
captioning is, well, wobbly in parts (e.g. "Hermione's levitating the 
feather, not Flitwick!"), there are some new shots.

1)Dumbledore holding baby Harry in a blanket
2)a fuller shot of Flitwick's class, showing that there are around 
25 - 30 students present
3)Hagrid's pink umbrella threatening the Dursleys (Hagrid's out of 
frame)
4)Harry bemusing a guard at Kings Cross asking for the train to 
Hogwarts
5)a new shot of Ollivander's
6)a new shot of Snape (Mmmmm)
7)a shot of Hagrid's hut, with Hagrid playing a pipe outside
8)Harry and Dumbledore in the hospital wing (which looks fantastic, 
proper old metal framed beds and screens...)
9)Draco and Harry being sorted, and a shot of the hall and the 
sorting hat
10)several shots of the Forbidden Forest which look unfamiliar to me.
11) Ditto for the Chess Game

What interested me the most, however, was a shot entitled "Everyone 
laughs as Seamus Finnegan's experiment goes horribly wrong in 
Hogwart's Great Hall"

It's a shot down the length of one of the tables in the great hall; 
the sudnets have books and quills out, and it looks like they are 
working.  Seamus is looking shocked, and a plume of smoke is rising 
from his open books.  The only people in shot who I could identify 
are Fred and George who are laughing, and Percy 9I htink) who is 
looking unamused.

Did anyone else get this pullout?  What scene could this be from?  Is 
it one of the Weasleys' practical 
jokes?  Or a Howler?
