Maybe you should learn how logic works before conflating my religion with actual science? I studied both at school, before coming to my own ideas.
1. Specific matter has specific behaviors. Metal is drawn to magnets, rusts (unless it's gold or tin), and can be pounded into shapes. Fluids (especially water), fits to the amount for the container. Gases can slip into tiny areas because each molecule is allowed its own movement. Solids block the flow of liquids (like ice preventing water from flowing to the other side of the stream). Acids tend to break down solid matter, but unlike in shows, only certain acids affect certain materials.
2. A horizontal curve created by fitting a container is not the same as a parabola extending into midair. Horizontal =/= vertical curve.
3. Water flows uphill when it is under high volume or high pressure (such as when pumped through a tap). This is not the same thing, at all, as what I asked. I asked if you have ever watched a waterfall flow in reverse or water bend (not around a corner, but in the unnatural way it would have to in order to comply with the requirements of a perfect sphere). In fact, the behavior of water you are describing is so unnatural, that I cannot even find a decent picture. There is a reason why water rides don't typically have "loops" like roller coasters, water would have to be pumped against its own flow at high force, or it would pool at the lowest point causing whoever was riding it to drown. It also tends to separate it the loop is enough. Water can be pumped uphill, it can be pushed downhill, but water looping generally isn't a thing without significant momentum or energy, and alot of risk. And if you do somehow manage that, you cannot have a water ride with an open top, not unless you want people flying off into space as the water drips out.
You notice that this has significant downhill force before even trying that? If the loop were bigger than the downhill, you might even get backflow, where the water tries to make the loop, goes backwards and merges with other water. And the water needs to be able to push a person steadily forward. Maybe if you pump enough, it can continue. Maybe people will drown on your ride too.
Most water rides look like this...
It tunnels, it turns, yes. It's also water flowing downhill. For an example water going "uphill" you're talking about a canal, where what is trapped and rises because it gathers. Thus is quite diff from what I mean.
This is a hill. Show me a hill of solid water not clinging to any earth, and I'll have no trouble believing your round Earth theory. Otherwise, you're wrong.
