Note that the house to the right is the home of many of our mass units. That they cannot be directly observed is persuasive evidence that our conversion formula is accurate. Witches, once believed to be rather small creatures, continually interfering with human beings, were habitually seen on Halloween against a backdrop of the moon. Recent evidence indicates that witches are gigantic creatures, nearly the size of the moon itself, quite close to the moon, and in continual orbit about it. It takes a witch 1 min and 45 seconds to completely orbit the moon.
All witches travel at the same speed.
At Halloween midnight, precisely, all witches stop moving, fall into the moon, and normal time resumes. The evidence suggests that witches are not responsible for the evil doings on halloween. Then the length of the wing shortens if it is moving away from the witch, resulting in a increase in velocity, but not without limit. The velocity may never exceed the velocity of a witch orbiting the moon. Any bat wing, or other object, once it attains witch orbit speed, promptly grows a broom and become a witch.
