Roman inverted siphons made water climb uphill—without pumps! 🤯💧

3-Second Blueprint (English)

1. Roman aqueducts crossed deep valleys by feeding water from an elevated header tank into sealed pipes descending to the valley floor.
2. Hydrostatic pressure peaked at the valley bottom, requiring thick conduit walls, sealed joints, and heavy masonry supports against bursting.
3. Gravity drove the continuous column up the opposite slope into a slightly lower receiving tank placed to offset pipe friction losses.
