I can't believe they wouldn't even let me hold a vote among the passengers about whether to try the loop.

How fast would the water have to be traveling for this to actually work? Pretty sure there was a waterslide built with a loop once and it infamously didn't work, but those work on gravity alone. With enough pressure it should be able to loop, right? Or would it just get wonky because it's a fluid? ๐Ÿค”

I feel like this could be one of those things that works perfectly if you make a small model, but won't ever scale up due to reasons.

I don't think he's done one with ocean liners but he did one with trains.

I was actually more curious about the water itself and forgot we were even talking about a boat lol. Could you force that much through an open loop without it sloshing back inward?

I feel like it'd need to go at super sonic speed.

Could you get 3 cats to do what you want? Maybe. What about 300 million cats? Water is like a cat sometimes lol
