When you are making a Time Turner, you must have gloves on. This is very important as the Sands of Time might get in-between your nails! Also, be careful not to turn it when you are making it, for you do not want to go back into a half-time. This is where two times are mashed together to make a new age. Another case is when you go back but only some of the things of that time are there. This happens because when you are making a Time Turner, not all of the elements are in place, causing problems with how it works.
