On Pottermore I can't complete the Potion (im i just being thick) или could someone help

Hi i used to not know were the wand was but its under the book that gives u instructions

Hi, I too am having trouble with the potion even though I have followed the instructions. I will keep trying. Pottermore will not let me Переместить out of book one and I have done everything in it and it is boring now.

Ты point your wand at the cauldron and lightningish stuff comes out! :)
