About this episode
If one takes out an object from one domain to another, one is obligated only if it is an item that is important. How is significance of an item determined? Is it subjective? Does it depend on what use you are intending for it? Does past behavior play a role? The mishna lists food for animals - what amount of each food item would obligated you? Each food is intended for different animals who each eat different amounts so the amount depends on the particular food. What if you take food for one animal to feed a different type of animal - what amount would be needed to obligate one? Can different food items combine to get to a requisite amount? For food for humans, what is the amount? Can different foods combine? What about parts of the food that are inedible? What is the requisite amount for drinks?
