Zephyr figured there would be some spell in place to keep them from sleeping, how else were they supposed to hold the sphere for such a long time? Unless that was the point, that they became so good at magic control they could hold the sphere in their sleep. He wasn't sure, but Zephyr didn't want to dwell on it, so he found himself a nice area of the room and started on making his sphere. He figured working on speed would be the better option to start with than duration. That way if he ever lost it he could just make it again nice and easy. He was excited to get training his magic, and after a couple of minutes made his sphere, it was orange. Interesting. He made it disappear then tried again and again until he could get the time down as low as he could.
