Huh.
This thing works *way* better than I would have thought. Further interestingness: apart from the plastic film and the rubber band, there’s nothing here that would have been unachievable by the Romans or any other iron or even bronze-age civilization, and there is probably a low-tech alternative for the plastic film (silk, maybe? Really thin paper?). The rubber band could have been replicated by pre-Columbian MesoAmericans since they were already makign things out of latex rubber; *maybe* Old World cultures could have made rubber from African sources, or used sinew or something.
