With a deep breath and her concentration on the rocket before her, Silvia casted the spell.

“Explaeris!” she said, and with those words she waved her wand in a circle above the rocket. She stood back at a safe distance and then…

FLAP FLAP FLAP, FLAP FLAP FLAP

The fact that her classmates were doing the same arm flapping motion as she was did not lessen the awkwardness of it, though it wasn’t as embarrassing as it could have been had she been made to do it alone. The rocket seemed to shake slightly as the air pressure inside it began to increase. FLAP FLAP FLAP. The pressure continued to build, until…

SWOOOOOOSHHH!!

The plastic rocket burst forth and soared into the air. At that point Silvia dropped her arms to her sides as her head turned upward, her eyes watching in awe.

That was awesome! The little Eagle wished she had some way of measuring the height of the rocket’s path; she wanted to experiment. What difference would it make if she were to change the wing shape or use a different kind of fuel?
