I saw a strange thing on antiques roadshow that I can't figure out. It was a small water fountain made of glass and metal that appears to make water go uphill. It is totally manual but I don't understand how it gets the water to squirt at a higher level than the water supply. On top was a round glass dish with the fountain in the middle which wasn't much more than like a squirt gun shooting up a couple inches and falling back. Below was a blown glass arrangement that looked exactly like an hour glass that is manually flipped over. According to them the water flows out of the top bulb to the fountain above it and drains back to the bottom bulb. When it's all out of the top glass bulb and in the bottom bulb it's flipped over like an hourglass and it cycles again. The glass bulbs, which actually looked like an hour glass had a pinched waist with the water feeds. They looked like they would hold 1 or 2 quarts at most each. The whole thing only stood about 2 feet high. The water came out about 6 inches above the upper bulb. It was working. What am I missing here. How does it get the water to flow uphill? Has anyone got any idea how this can work without any power other than just flipping over the water reservoir? It seems to defy gravity. edit: I think I figured it out right after I posted this.
