Pardon my nerd talk!

The JK Rowling site is freaking awesome.

But I can't find anything. I found this one beaker full of red stuff, which i clicked on and it disappeared but didn't do anything.

There's one part where you use the eraser on the blank page and it reveals a formula.

What do you do in the room after you click on the hair tie thingy?

Somebody tell me where the extra stuff is PLEASE!

My scrapbook is totally empty.

I swear I thought that was her in CoS.
