During that day, Ron, Harry and Hermione read and reread the spell. "We need to learn this wand waving sequence," Hermione said, pushing a loose strand of hair behind her ear. She looked up at the boys with a frown. "It looks difficult," she said grimly. There were diagrams of a wand at each stage of the sequence. Hermione read a segment from the book, "If more than one person is performing the spell, all must perform the wand segment of the spell in perfect synchronisation. The more people performing the spell, the more powerful it is. A flash of light will be emitted as the spell is completed, though it is so rapid, one would miss it if they blinked."

Over the next one and a half weeks Harry, Ron and Hermione practised the wand waving sequence over and over again. They needed to learn a series of twirls and patterns, which were to be performed individually. Then they were to put their wand tips together, before joining hands and chanting the spell. They could only stay in the next dimension for 24 hours.

Finally, they felt they were ready. Hermione felt like she had swallowed Mexican jumping beans. It was all she could do to hold in her excitement. They went into a secluded part of the library and stood the required length apart. They were all nervous. Hermione took a deep breath and began chanting the spell softly. "Skipedia dimensa, skipedia dimensa.." Harry and Ron joined in. They began the wand waving sequence, which they knew so well they could do it with their eyes closed. After that part was over, they moved in and tightened the circle as they joined hands. They had to repeat the chant 5 more times for the spell to work. "Skipedia dimensa, skipedia dimensa, skipedia dimensa, skipedia dimensa," --One more to go!-Hermione thought excitedly, her heart racing. "Skipedia dimensa!"

Suddenly the floor under their feet gave way, and they were swirling rapidly in a seemingly downwards direction. Hermione's stomach lurched, it was like riding downhill on a roller coaster. All three had their eyes wrenched shut, and were holding hands tight enough to cut off circulation. Then, as suddenly as it had started, it stopped. Hermione was the first to open her eyes, and found herself in exact same place as they had left. Her heart sank as she assumed the spell had failed.

She blinked back tears as a wave of misery washed over her. They'd tried so hard. What had gone wrong? She looked at Harry and Ron, expecting to see disappointment on their faces, but got the surprise of her life to see their astonished looks. Their eyes were diverted to something behind her and their mouths were open. Very slowly she turned, and gasped at what she saw.
