In this video, Wide Open Spaces shooting video contributor Jeff, a.k.a. Taofledermaus, responds to viewer requests about a previous video in which he tested gallium-tipped shotgun slugs. This time, he managed to create slugs entirely out of gallium using fan donations via Patreon.
Here’s why this is really cool:
It is one of the most brittle metals there is, and it can shatter at the lightest touch. That’s why Taofledermous coated his gallium slug in aluminum to make sure it didn’t disintegrate before hitting the target. Yeah, that’s a unique property for any material. But it gets better.
Gallium also has a very low melting point, so a piece of Gallium will actually start melting if you close your hand around it.
Not only that, but it also reacts with other metals (including steel), “attacking” their structure and making them more brittle through contact. Finally, gallium has still more properties that allow it to help stabilize plutonium in the cores of nuclear bombs.
Yeah, science is pretty cool, especially when it comes out of the barrel of a shotgun.
