I would love to see it with the image rotating at the same rate as the arms, so that the perspective changes to a rotating reference frame.

Ok now I want to know if this will do the same with lasers instead of streams of water. I assume a much greater rotation rate will be required.
Samuel Underwood 8 month ago
Here's a way to intuit this result: If two objects are in circular motion with the same tangential velocity, but with different radii, the one with the smaller radius will have a higher angular velocity, which means it will complete the circle in less time. Think of a helicopter blade. The end of the blade has a much higher tangential speed than the base even though both parts of the blade complete the circle in the same amount of time. If you decrease the radius, but keep tangential velocity the same, you get a greater angular speed, which explains why the water moving inwards leads, while the water moving outwards trails.

Destin i love your open humble approach to seeking out disagreement and checking arrogance. i relate nearly fully, but have not as much success as you demonstrate. sure can appreciate the real work there. thanks for being so bold. great example for all of us.

When Steve was talking about the notion of "in a snapshot" he should've said "the expelled water pattern in relation to the nozzle". It's all about the point of reference in physics.

I was taught that this is referred to as the “I’m an expert” trap...and it catches us all, from time to time. Our personal experience mutes all others’, for ours, to us, is most important. Cultural projection clouds the perspective, as well. There are many “right” answers, but we should focus on the many correct outcomes.

Hey DESTIN. There is a video called “spinning t handle in zero G”. Very interesting. I would love to hear you explain why spinning it in one direction cause it to intermittently spin on a different axes

Haha when I first thought about the simpler one I was like "Oh! It's just a simple vector addition" but since I only slept for an hour today thanks to construction, that was as far as I got.

“When I disagree with someone, it is imperative that I stop, I listen, and I don’t move on until I completely understand the other person’s perspective.” The experiment was awesome, but this profound insight at the end really hit home. If anyone ever asks me what it means “to have character”, I think I’ll link them this video.

Feels like you forgot to mention why the water travels ”ahead” when spraying inwards and ”behind” when spraying outward. The answer is simple geometry, when spraying inward the ”radius” decreases so the droplets travel faster than the shaft (since they have the tangential velocity at the tip). When spraying outward the ”radius” increases and the droplets travel slower than the imaginary extension of the pipes. Sure, just saying ”look at the resultant of velocities and remember that unless acted on by a force everything travels straight” explains the phenomena, but I feel like the simple geometry aspect explains the ”optical illusion” which really isn’t an illusion, the water is really shooting out in front and lagging behind the pipes, if you were to place something there (in the same rotational reference frame) it would become wet, so not really an ”illusion”.

"In real life"? Oops! Even when you see something real on a video about real things in person, it IS in real life. Just because you're not in person with it yet doesn't mean it's "not in real life." Please don't get real life mixed up with being in person.
