This is the "annoying" part I was referring to. Eventually I'd like to have a space just for welding, grinding, anything that will spark, all of it ventilated and away from explody stuff. That's a luxury for me, and an impossibility for many people so yeah, stick is simple, and a GREAT way to learn, but to be safe about it there's other steps involved, and with it raining most of the year and the stuff that sparks would damage in the limited indoor space, it's a hassle and checking the weather report for a good portion of the year. Summer, yeah, that's easy, just keep it away from the grass and hydrate, every other part of the year, pain in the bits.

welding is fun, but annoying to set up and do casually. For similar fun that also comes with toxic fumes, try stain glass lead work or plastic welding. All of these are basically just melting like materials together. it's mostly just different heat sources and materials.

Plastic welding is remarkably fun and can be done with a soldering or wood burning iron. Lots of plastics can be had for free if you learn the plastic names and materials usually printed somewhere on most plastic objects for recycling purposes.

Is it possible to hoard enough water in one place to throw off the balance of the earths rotation?
