Nina watched her classmate's attempts. There's seemed to last longer than hers.

I'm just not concentrating enough. There's no one else in the room. Just you and me little unicorn.

"Geminio!" She exclaimed, concentrating hard on the fact that there will be two when the incantation was completed.

As she watched, she saw another flash of pink. But this time she could clearly make out a horse-shaped outline.

Yes! Good. Again!

Still concentrating hard, "Geminio!"she repeated.

And again a flash of pink, and the outline of the unicorn. The more she tried the more details she could make out.

So it's true. Practice will make perfect.

"Geminio!" She said once again as the unicorn definitely appeared before vanishing almost a full second and a half later.
