    Which is heavier: a pound of lead or a pound of feathers? 10th Jul 17 at 9:14 AM
    Well, according to some research done, it might actually be the pound of lead!

    At least perceptually, as found in this blind experiment............


    QUOTE
    Is a pound of lead heavier than a pound of feathers
    ?


    A pound of lead feels heavier than a pound of feathers, a thing long suspected, but not carefully tested until 2007, when Jeffrey B Wagman, Corinne Zimmerman and Christopher Sorric ran an experiment involving lead, feathers, plastic bags, cardboard boxes, a chair, blackened goggles and 23 volunteers from the town of Normal, Illinois.

    The scientists were based at Illinois State University. In a study published in the journal "Perception", they explained why they took the trouble........ '"Which weighs more – a pound of lead or a pound of feathers?'
    The seemingly naive answer to this familiar riddle is the pound of lead, whereas the correct answer is that they weigh the same amount
    .



    "But, they wrote, "this naive answer may not be so naive after all. For over 100 years, psychologists have known that two objects of equal mass can feel unequally heavy depending on the mass distribution of those objects."




    Wagman, Zimmerman, and Sorric poured some lead shot into a plastic bag, then sealed and taped the bag inside the bottom of a cardboard box.
    Then they stuffed a pound of goose feathers into a large plastic bag. This fluffed, baggy entity entirely filled a box that looked just like the box with lead.

    Then came the test. One by one, the volunteers sat in the chair, donned the blackened goggles, then "placed the palm of their preferred hand up with their fingers relaxed. On a given trial, each box was placed on the participant's palm in succession. The participant hefted each box and reported which box felt heavier
    ."


    Slightly more often than not, the volunteers said that the box with lead in its bottom was heavier than the box with feathers spread thoughout its innards.



    After weighing and judging all the data, the scientists educatedly hazarded a guess as to why one box seemed heavier.
    Probably, they said, it's because:




    "the mass of the feathers was distributed more or less symmetrically in the box (ie the feathers filled the box), but the mass of the lead was distributed asymmetrically along the vertical axis (the box was "bottom-heavy"). Therefore the box containing lead was more difficult to control and it felt heavier."

    The scientists did not test how volunteers would respond if the lead were fixed precisely in the middle, rather stuck to the bottom, of the box. This they left for future scientists to contemplate.

    This is a debate that raises a whole lot of new set of questions, as well as put a new spin on the possible issue of new Cod Wars taking place.

    Can these furren cod claim refugee status given they are having to migrate due to global warning?
