    If you’ve ever used a siphon to drain a fish tank, it’s a similar concept. I believe the entrance is a bit higher than the exit, so I guess gravity and water pressure?

      Not disagreeing with you there, but if you’ve siphoned something you’ve probably done it with a polymer, how the heck were the Romans doing it? You can’t get intestines sealed together tightly enough back in those days.

        The Romans would often use lead or clay pipes with either dirt or concrete packed around them to make a solid seal that would resist the water pressure and not burst the pipe like a ripe fruit.
