Metal Meltdown | Brainiac75
Can metals be melted in hot water or just by the heat of a human hand? Some can and in this video I melt a bunch of them! Here's where I bought the samples if you are interested in trying this yourself: (it's much better in real life than on video ;) www.crystalgrowing-shop.com (German site, most is available on eBay too) - Rose's metal - Wood's metal - Bi-Pb-In-Sn-Cd (in rare cases called French's metal) www.smart-elements.com - cesium - gallium in vacuum ampoule www.eBay.com - gallium - Field's metal The mercury is from antique mercury thermometers. Link to the Hg-Tl pictures I use with written permission: http://www.periodictable.ru/081Tl/Tl_en.html If you are interested in elements you should check out the rest of his website. His thorium sample is the best I have ever seen! There are only few sources about the very specialized Na-K-Cs alloy. I have since the making of this video found another source that mentions these compositions and melting points: 12% Na, 47% K, 41% Cs = Melting point -78 C 3% Na, 24% Na, 73% Cs = Melting point -76 C So no doubt that Na-K-Cs is the metallic alloy with the lowest melting point at around -78 C, but the exact composition is a bit of a mystery...
