I switched to buying sparkling water in aluminum cans. As much fun as it is to make plastic string from bottles, I now have more string than I know what to do with (I have ideas, but not the time yet!) But aluminum is one of the few recyclables that actually make money (it is easier to melt recycled aluminum than it is to mine and process bauxite and recycling reduces the need to strip mine for bauxite). We don’t have recycling where we live, so the choice of containers makes a big impact on the amount of trash we produce.
I have some ideas on things to make with aluminum cans, but again, the time to process and make has been thin (chickens). I took a large bag to the middle school science teacher for a high/low pressure experiment (and the school has recycling, yay!), but it didn’t take long to build up another big bag. I called around and the local scrap yard takes aluminum! And pays for it. What? Not much, but still, it made me rethink my bag of uncrushed cans. A 33 gallon bag full of empty cans weighs about 7 pounds. Crushed we can at least double that, and reduce the amount of space taken up in the house while the cans are waiting for recycling.
So I looked up DIY can crusher and the first hit was a good one. I gathered some 2×4 scrap, a spare gate hinge, and two pint canning jar lids. All from around the house.

Then my kids and I made it a project. We set the hinge on the ends of the 2x4s, and used 1 inch screws to set the jar lids as guides between the 2x4s. They each took turns using the drill to set screws, then they took turns putting in cans and stepping down to crush the cans.

We started off with the screws that came with the hinge, and after a few cans, changed to 1 inch screws, then to 2.5 inch screws. I think in the original video the guy used lag screws, which would be even better (but I was out of those). The jar lids took a beating, but still worked well!
