    Go ahead, pick it up.

    I attended a large Christmas party with my new girlfriend and had the aluminum and Tungsten cubes stacked with the Aluminum on top. I first got the children to pick up the lighter cube and feel its heft. Most were familiar with aluminum and thought it was interesting, but not all that much. Then, I asked them to set it down and pick up the tungsten cube. All of them were astounded at the contrast between the two. I also had the sphere there for them to experience and everyone at the party really enjoyed the novelty of feeling something so heavy in such a small package. I explained that there were few metals heavier than tungsten, but gold was one. If a cube of gold that size were available to purchase, at today's price of gold, it would cost just under $50,000.

    Delightful Desk Dohickey

    What great paperweight and conversation piece for your desk. Weighs over 7 times more than the free included aluminum cube of the same size. Provides a dramatic illustration of the force of gravity and encourages thoughtfulness about how this force interacts with matter. My only wish would be that more care was taken in manufacture, handling and packaging to eliminate, and prevent nicks and blemishes. My nicks were primarily on a couple of the nicely turned edges, so they are not too noticeable.

    When you feel the weight of this cube in your hand, you think WOW! and start to consider how gravity affects us every day, and how physical properties of materials, such as mass are so important in our world. The cube is so simple, but the concepts of mass and gravity (resulting in weight) are so complex.

    I have no clue why, but this cube is really neat. It is freakishly heavy for it's size and is a great conversation starter as it sits on your desk. Expensive...but hey...it's tungsten.
