Watch an 110-Pound Iron Anvil Float on Liquid Mercury
Seeing an anvil might throw you back to your childhood days thanks to one Wile E. Coyote who made the object a relic of popular culture. In this video by the YouTube channel Cody'sLab, this heavy and dense object can be seen floating in a tub full of liquid mercury.
To do the demonstration, he finds a large tub and fills it with mercury. Then, he drops a 110-pound (49.9-kilogram) iron anvil in it to see it float. This might surprise you, but it really shouldn't since mercury is so dense that elements such as lead, silver, and copper would also float on it with ease. The YouTuber states that it floats better than wood floats on water.
Not only it is extremely satisfying to see how the liquid mercury doesn't stick to the anvil, but the reflective surface of it shining on your eyes will also make you appreciate the excellent demonstration.
