pH effects on vegetation

8 inches diameter by 4 inches tall for gas collection over water

sized for high-turn-count solenoid construction where 500g of fine wire feeds multiple project builds

providing dense uniform spheres for ramp-and-collision experiments where a heavier projectile is needed than the plastic marbles can provide
