Greetings fellow nerds. In previous years i’ve applied gallium to various aluminum objects and have destroyed them that way. This year let’s try something a bit more common, a baseball bat. For those of you that don’t know, baseball bats are used to motivate people that owe you money. Most are made from wood but you can buy aluminum ones as well and that’s what i have here. They are necessarily very strong and it is incredibly difficult to damage them with just your own strength. Now before we apply the gallium we’re going to need to file off the surface of our aluminum baseball bat. Primarily we’re doing this to get rid of the paint and we and we want to remove the aluminum oxide layer underneath. Gallium destroys aluminum metal easily but has a difficult time penetrating other materials like paint and aluminum oxide. Now we don’t need to remove all the paint, just enough to ensure the gallium can get at the aluminum underneath. Here we are, one partially filled aluminum bat and i’ve placed it in a glass beaker. Now for the gallium. I’ve previously melted this gallium by keeping the bottle in hot water. Gallium is an interesting metal in that it has a very low melting point, just 29.76 degrees celsius. So with just a little hot water you can have a liquid metal without the dangers of high temperatures. It kinda resembles mercury in how easily it pours. Okay so we have our bat immersed in gallium. I’ve turned on the hotplate to about 70 celsius to keep the gallium molten while it diffuses into the aluminum. This will take some time so i’m going to come back in a couple of days or so. And here we are. Let me get it out of there. Looks like we still have a lot of gallium left. Let me set that aside. And here is the baseball bat. We can see the overall structure is still intact but there is some deep cracks and holes right through. Okay, let’s see just how strong it still is. That was a lot easier than i expected it to be. I’m not from the planet Krypton, i’m just from Canada. So what’s happening? The gallium metal is diffusing in between the grain boundaries of the aluminum microcrystals and disrupts their bonding. Being unable to bond together the aluminum is rendered extremely weak. Some of the aluminum also dissolves into the gallium to form an alloy. Some people say it’s an amalgam but that’s a misnomer. Amalgams are mercury based alloys. Just like steels are normally iron based alloys. While some specific gallium alloys have specific names like galinstan, as a class, gallium alloys don’t have a special name and they’re just called alloys, they’re not amalgams. Interestingly enough, the structural damage induced by the gallium is going pretty far through the baseball bat. The gallium soaked through the metal like water soaking through tissue paper. I don’t know about you, but it’s amazing to me to have something as solid as a metal bat behave like it was porous. Ok now as i keep breaking the aluminum to the handle, it’s getting stronger and stronger. Looks like i didn’t leave it long enough for the gallium to diffuse all the way through. On a side note, don’t worry about my glove tearing. Gallium is non-toxic to skin, i just wear gloves to minimize on the mess. Okay, looks like this about the limit for the damage. Anyway, so this is what’s left of the aluminum baseball bat. This pile of very weak aluminum infused with gallium. So there you have it, gallium induced structural failure of an aluminum baseball bat. Thanks for watching.
