Another round of party planning

Just to prove that I really have become an uber-geek, I am in the process of organising a Harry Potter party. 

At nearly twelve years old, the kid has become simply too cool for school. Birthday idea after birthday idea was shot down. Then I struck a winner.

A movie at the Imax, followed by a play, get-together in the park. Obviously not a play because that would not be cool. Even though it is in a playground....

As a happy coincidence, the party is just two days after the launch of the latest installment of Harry Potter. Tickets have been bought, and a party is being planned. Invitations are going out way ahead so we can send out a second round if need be (don't want to waste those tickets).

I think the key to a tween party is to be low key. Oh the embarrassment I could inflict without even trying. The invitations have been printed on parchment paper, and tied with a simple black ribbon. The Harry P font was downloaded from here, true home of Harry Potter geekery. I had thought at first that I would write it in Potteresque language, but I think that would be taking it just a little too far. Don't want to be uncool after all.

The little cauldrons were a happy find at Spotlight, on sale pre Halloween. These will take the place of lolly bags, and will be filled with creepy crawly sweets - spiders, frogs etc. I also like the idea of these.

It's about now that I have to confess that I have not actually read a single Harry Potter book, or seen any of the movies. Do you think it's necessary for the movie to make sense? It is after all, two and a half hours long, and I don't really want to be confused the whole time.

As for cake. Hmmm. Stumped. I haven't seen anything in the theme of Harry potter that I like. Given that it will be cut and eaten in the park, it need to be transportable too. Thinking caps are on. Any suggestions?
