	Make Bismuth Crystals  Here I show how bismuth crystals can be made at home. Feel free to contact me with questions/comments. EDIT: Mystery solved! The lack of oxide layer is due to the presence of tin. I used to experiment with different alloys of bismuth and tin and I guess when I was melting all the pure bismuth pieces back together a piece of tin got in. Huge thanks to Jeffery Schwartz from amazingrust.com for taking his own time to analyze my sample in an Energy Dispersive X-ray Spectroscopy machine, which confirmed the presence of tin! 2011年05月09日再生回数 14065

	Diamagnetic Levitation 2 - Bismuth  The first shot shows the setup of this experiment. One big cylindrical magnet, made from neodymium (NdFeB), is hung at the top, above two plates of bismuth. Bismuth is element nr. 83; a highly diamagnetic metal. Diamagnetic means that it creates an opposing magnetic field if there is a magnetic field close to it. That means that it will repel a magnet. The small cube between the two plates of bismuth is also made of neodymium (NdFeB) and measures 5x5x5 mm. The two plates of bismuth repel the magnet, but they are not strong enough to overcome gravity. This is solved by the big cylindrical magnet on top of it all attracting the small magnet. If all elements are aligned carefully, the small magnet will float stably between the two bismuth plates. You can easily push the magnet and it will go back to the center. It can spin for hours! 2010年04月14日再生回数 41368
	Bismuth Plates  New Product From AVA Magnetic Levitation. Australia pty. Polished bismuth plates under $50 AUSD the plates come in a pair combined weight is approx 300 grams comes with instructions of care and basic plans to build a Diamagnetic suspention levitation display/experiment. Now also 1X rear earth magnet 6mmX5mmX3mm gradeN46 Its the same as the one used in this Video to make the levitating magnet spin using the power from a lamps tramsformer. Manny different setups can be done with just a basic display rig like the one in this promo that was built from the basic plans provided with this product. the rig was built in less than 2 hours at a cost of less than $12 AUSD also the height of the levitation depends on the strenght,size,shape of the top magnet and the size,shape and strenght of the magnet to be levitated so all these factures are up to the builder to select. But a good bacis rule to follow when picking magnets for a Diamagnetic suspemtion levitation rig is (Large ferrite ring magnet for the lifter and small rear earth magnets for the levitation )This combo always gets good resaults sofar we have been able to levitate a magnet over one polished plate almost as hight as its own hight. We hope this product meets all the expectaions of customers requirments as much work has been done to get this hard to work with element to this high quality state and we are committed to further improvments to this product and all our others all the time and will soon have finnish the ... 2009年03月07日再生回数 16399
	Bismuth Diamagnetic Properties  Bismuth (element no. 83) is one of the weirdest elements. Though encircle in the periodic table by other heavy elements with infamous toxicological history, Bismuth is considered the least toxic of these metals. Bismuth is known for many strange properties - this video demonstrates its massive diamagnetic behavior: Bismuth is repelled by magnets but for demonstration it is recommended to use rare-earth magnets, as kitchen-magnets are all too week. Bismuth is rather expensive but for educational purposes it is worth consideration. For electromagnetic, physical, chemical and artistic purposes it is eminent. For artwork and metal casting it is a wonderful replacement for the toxic Lead (Pb). Furthermore Bismuth forms low melting alloys with many other metals. In its pure form it is very brittle, with a reddish luster. Cooled slowly it forms large, beautiful crystals, covered with oxide layers in the colors of the rainbow. Etching the surface to see the crystals can be done in a dilute solution of hydrochloride to which is added a small amount of hydrogen peroxide (1 part of HCL poured slowly in 3-5 parts of water. Then you add 1 part of 35-40% H2O2). Dipping a piece of slowly cooled Bismuth in this solution will remove the oxide and reveal the beautiful crystals. The slower the cooling process is, the larger the crystal will be. Enjoy the fun! 2008年06月19日再生回数 26188

	Isolating Bismuth metal from pepto bismol  In the episode we isolate bismuth metal from a few bismuth tablets. To crush expectations, it is cheaper to buy bismuth then to use this method. For a 5 dollar 480ml bottle, theres is 4 grams of bismuth. by the time you spend that you can buy 4 ounces of bismuth for the same amount.

	Heart of Bismuth  Heart of Bismuth - Bismuth is a very strange element. Besides its peculiar physical and magnetic properties (view my other videos), pure Bismuth reveals large, beautiful crystals when etched with the right acidic solution. --- On Request I hereby reveal my experimental secrets: My "secret acidic formula" (wich isn't that secret after all - it's just a question of reading inwards - and experimenting A LOT) I have developed has a large number of potential applications. It seems to attack and remove the protective metal-oxide on almost any metallic surface. Furthermore it seems to attack, colorize and etch metals, that ought to be "unetchable" (almost like Aqua regia or aqua regis (Latin for king's water), though not as agressive and dangerous for humans) I don't know all of it's possible applications, so please do some experiments and let me know!;-) Now here it is: apx. 3 % HCL apx. 3 % H2O2 ... and the rest (94 %) is water. How to prepare a solution? Lets say, you have access to (1) 30% HydroChloride Acid (Conc. HCL in water) and access to (2) 35% H2O2. Then you mix one part of (1) with one part of (2) with eight parts of water. This gives you a ratio (HCL:H2O2:H2O) of 3%:3,5%:93,5% Lets say, you have access to (1) 30% HydroChloride Acid (Conc. HCL in water) and access to (2) 3% H2O2. Then you mix one part of (1) with nine part of (2). This gives you a ratio (HCL:H2O2:H2O) of 2,7%:3,0%:94,3% Using 6%:6%:88% and stronger solutions can result in unpredictable, but rather ... 2009年03月12日再生回数 9245
	PIERRE BISMUTH  French artist Pierre Bismuth was recently in Perth to launch an exhibition of three works, where Bismuth deploys humour to disorientate the viewers' understanding of cultural forms like print media and film. Cut & Paste caught up with him at the Fremantle Arts Centre to dicuss his works and the ever changing world of contemporary art. Bismuth shared an Academy Award with his co-writers, Michel Gondry and Charlie Kaufman, for Eternal Sunshine of the Spotless Mind in 2005. Distributed by Tubemogul. 2010年06月08日再生回数 1026
