Aerosol cans have long been one of those items that there is simply no way to functionally repurpose. They’re pressurized and will explode if they’re heated, even if all of the aerosol is gone because there’s nowhere for the air in the can to escape to.
But several artists independently became tired of throwing so many cans in a landfill that they came up with some alternate uses. And at least a couple of us waste-wary homesteading types did, too.
But before we get started and somebody decides to flame me for suggesting going against manufacturer instructions and opening a spray can, let me say one thing. Hey y’all … watch this! Just kidding, but seriously, I feel the need to start with the warning in order to make our legal team happy. You’re doing this at your own risk.
