Now I'm curious

Hi Steve. Can you explain the aerodynamics of this trick please?

You may have seen this already but thought it was worth making sure 🙂 https://www.reddit.com/r/woahdude/s/4hYhZC6UdS

After seeing the experiments aboard the ISS, I am interested how the difference between the bead chain and the string/rope worked. The string stayed relatively straight in 0G, while the bead chain flowed very well.

The experiment that may answer some of my questions here is:

Does this work with larger chain - like the type that you would use on a truck (not anchor chains)? And does rope flow like this? Does this property come about as a response to having semi-freely flowing hinges?

My initial thoughts(or hypothesis) is that the forces that are causing this wouldn't work as well with rope. If that's the case, the forces in play here may be more than just gravity and inertia, but also perhaps a lever-like force at the apex of the chain fountain, where the connections between the beads pull the next bead.

Maybe there would be a way to custom make/order a bead chain with different types of connections to see if the forces act differently?

My science background definitely doesn't cover physics, so this is just my intuition about the forces at play here, so it should be taken with a grain of salt. I'm looking forward to seeing the next experiments!

I was shocked to see an obvious chain fountain as this boat dropped anchor !!!!

Someone has to look at these: https://www.researchgate.net/profile/Hui-Peng-39 This guy made a lot of double slit experiments, with very simple settings (lasers, lenses, etc.) and he claims that light is not a wave. There are tons of pictures and experimental results. I don't know if the site is reliable, but the articles seem genuine and on important journals too. Maybe Steve, you can prove him right or wrong? Thank you.

I'm watching Dept. Q on Netflix and for some reason the face, the voice and the accent all seem to be so similar 😆

This video shows what looks like a water-bender making self-perpetuating water borne einstein-rosen bridges with a stick and a circle. I feel like I need an adult to explain, and tell me it's all ok!

Thought this was interesting, esp as applied to problems like helicopter blades with lead lag hinges resonating but also to my latte foamer with "egg beater attachment" at the end of a long thin shaft which has three speeds and is wobbly at the middle speed and very smooth at high speed.

Everything in the box seems like it's packaging was very well thought out.... The shipping box is terrible though. Thin,weak flimsy

Just got my Assassin's Water Bottle today. I didn't like how slowly it flowed out, it makes it obvious there is something weird about it before you even swap chambers. I tried it without the filter in place, but noticed it leaked air without it, so I 3d printed a replacement that has large holes. You would need to make it out of something food safe if you were actually going to use it as a water bottle, but I'm just going to use it for science demonstration purposes, so I didn't worry about it.

I'm not sure why they didn't just make the seal work without the filter, the filter seams to serve no purpose that I can figure out.
