The Deathclaw Gauntlet aka: Murder Glove. A staple of the crafting bench in Fallout 3, these days the Deathclaw Gauntlet is a little bit harder to come by for the average Wasteland citizen. But if you follow these steps you can get your hands on one for the mere price of killing a Deathclaw.
An isobar refers to all of the nuclides of all elements that have a particular atomic mass. For example, helium-6 is one of the many isotopes of helium. The isobars of helium-6 are hydrogen-6, lithium-6, beryllium-6, and boron-6. (Note, hydrogen-6, beryllium-6, and boron-6 are unbelievably short-lived).
This tool is called an isobar. An isobar is a line on a map that shows a meteorologist what the pressure is at the surface of the earth. They are lines that connect equal points of pressure. Isobars can be used to map atmospheric or air pressure in a way that makes it easier to understand. But first, what is atmospheric pressure? It's basically the force of the atmosphere on the surface of the earth, and it is caused by gravity.
