Precision Machined Tungsten Spinning Top: This spinning top is the perfect union of aesthetic beauty, precision engineering and an extremely dense, naturally occurring element - Tungsten. Tungsten, also known as wolfram, is a chemical element represented by 'W' on the periodic table with an atomic number of 74. It is a shiny and silvery-white metal with a density comparable to gold and uranium. This top makes the elements interactive and is a fantastic example of physics in real life. See how that mass keeps it spinning! You will get the best results by using metal or glass as a spinning point. This is a very unique and novel item - a great gift for that person that has everything. Watching the top spin is very relaxing and mesmerizing. Try it!
