Check the listing for details. Red Dirt Derby Tungsten Spinning Top. Condition: New. Listed at 29.99 USD. 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 (1.7 times more dense than that of lead!!!). This top makes the elements interactive and is a fantastic example of physics in real life. See how that mass keeps it spinning! The top spins at least two minutes by hand with practice, longer using alternative methods. 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!
