Back in the day, we'd just toss used sand after a pour. Now, we have systems to clean and reuse it, which cuts down on waste big time. It's crazy how much less we send to the landfill now. Makes me appreciate the changes, even if it was a pain to adapt at first.
Nah, I never got the clean hands thing. It was always gritty for hours after, like the sand was glued on. Felt like I was just moving the mess from the box to my skin. Efficient maybe, but not exactly clean.
