Olly was pleased that his answer had been a reasonable one, even if it hadn't been creative enough to earn him points. But the answer to his question did not really help. In fact, it just made him more confused. "What makes them explode then? Is there a spell?"

As they went further into the forest it grew darker and darker. Olly took out his wand and whispered "Lumos." That was better. After a while Olly's feet were gstarting to hurt, but he was trying not to complain. He kept telling himself they would be there soon. Soon. Soon? When they finally did make it he breathed an audible sigh of relief. He shifted from side to side, trying to take the pressure off his feet, as he listened to the instructions. They were going to be moving some seeds from one cave to the over. That didn't sound too hard. But the prospect of explosions and burns was a bit worrying. Olly quickly put on his gloves as he was instructed.

Okay, a spell. A very dangerous spell apparently. He definitely didn't want to burn anyone else, or get burned from someone else. He would practice and really try to focus. The wand movement didn't seem to hard, and he worked on that first. Move only the wrist. It took a few tries but eventually he got the hang of not making the movement too big. When he was satisfied with that he could practice saying the spell. "Chaw-den-sis." He drew out each of the syllables the first time. That wasn't too difficult. "Chawdensis."
