Putting old board questions into ChatGPT

Now my AI isn’t good enough? I can’t access it on this computer, so someone else can run this one through the Chatbot.

Bascially, it is “Picture a hollow S-shaped tube, with a flexible joint in the middle, perpendicular to the curve of the S. If you pump water through the joint into the tube, it will come out the ends of the S. Pump it with enough pressure, and the S-shape will start to spin backwards, like a lawn sprinkler. Now take this same apparatus and put it underwater. Instead of pumping water out, create a vacuum, and suck water in. Which way will the S shape turn?”

The original thread, and current debate, gives three equally-likely answers, and not a whiff of agreement on any.
