Procedure

1)Weigh the orange

2)Weigh the paper and  foil paper which is being used to dry the orange in.

3)Cut the orange in very thin slices to speed up the drying process.

4)Spread the slices over the paper, which is placed on the  foil paper. 

-Keep it in a warm place until it is fully dry. You can expect it to take 4-36 hours depending on the heat and airflow. In this way we completed the drying process in 10 hours.

5)Weigh the orange slices once fully dried. Don't forget to deduct the weight of the paper and the  foil paper if you are weighing the orange slices with the paper and  foil paper.
