It would be interesting to hear the science teacher's opinion on this. Maybe they were doing a chemistry unit and just the day before the kid asked "What would happen to powdered sugar if......" and she gave him the go-ahead to bring some in. On the other hand, if they are in the middle of a study of outer space and he had never said a word to her about sugar, well, that raises some questions right there.
Again, since the school system is required to be mute, the world may never know.......
