Two Dozen Cans by Luke

Two Dozen Cans by Luke - October 2026 Scholarship Essay

I go through a lot of Trader Joe's canned water, and for most of high school, the empty cans have ended up in a pile on my desk. Sophomore year, the floor started filling up too. The e-waste club I'd helped start was taking in donated laptops and fixing them up for students who couldn't afford one, and the ones waiting on repairs ended up in my room: Chromebooks, scratched-up ThinkPads, most of them with only one thing wrong, like a dead webcam, a cracked corner, or a hinge that wouldn't hold the screen up anymore.

I'd gone years without a computer of my own, and I paid for the one I have now with tutoring money, so I wasn't about to give up on a laptop over a hinge. The problem was the part. To make a new hinge, I needed a block of aluminum, and the one I found on Amazon cost $100 for a two-inch cube. I didn't buy it. I opened another water instead, and when I finished it, I picked up the empty can and started wondering how much aluminum was actually in it.

Not much, it turns out. A can is about fifteen grams. A two-inch cube is about 350. That works out to roughly two dozen cans, and there were a lot more than two dozen on my desk.

The first batch did not go well. Once the cans heated up, the paint burned off in thick grey smoke, and my mom could smell it long after the smoke was gone. What I finally poured out was a small, lumpy puck. About half of the metal I'd put in never made it. It had turned into a grey crust that wouldn't melt.

I didn't understand what had gone wrong, so I started reading. The grey crust was aluminum oxide. A can's walls are so thin that the hot metal has a huge amount of surface touching the air, and it reacts with oxygen before it ever gets the chance to melt. Aluminum melts at around 660 degrees Celsius. Aluminum oxide doesn't melt until past 2,000, so anything that turned into crust was gone for good.

It also turned out that "aluminum" isn't really one metal. Cans are made from an alloy called 3004, which is soft enough to be stretched into walls about as thin as paper. The hinge I was replacing was 6061, a much stronger alloy used for things like bike frames. No matter how well I melted them, my cans were never going to turn into 6061.

For the next batch, I cooked the paint off before melting anything and crushed the cans into small, dense bricks so less of the metal would touch the air. It still took two more tries. On the fourth batch, the metal that poured out was bright silver, with almost no crust at all.

I made the new hinge from that batch. It was softer than the 6061 it replaced, but a laptop hinge doesn't need to hold much. When I put the laptop back together and opened the lid, the screen stayed where I left it.

It went out with the next round of donations, and I don't know who has it now. Whoever it is, their screen is being held up by a few of my old water cans. The same ones I still drink every day.
