- agumonkey 6y agoPretty nice. I'd love to make a spinning variant.
- ta1234567890 6y agoAmazing video, thanks for sharing. Now imagine a round/spherical version of that liquid band, but instead of getting the vibration from outside (the glass walls), the vibration is coming from inside, and you pretty much have a model for Earth and an alternative model for gravity.
- ben_w 6y agoDoes this alternate model do anything useful, or have you just done a Fourier transform on a graph of the inverse square law?
- ta1234567890 6y agoGreat question. What does the Fourier transform on a graph of the inverse square law look like? Would love a link if you have one.

- ta1234567890 6y agoThank you, that was fast! Looks linear when != 0, I would have expected it to be an oscillating function, if it's meant to model the effect of the vibration on the liquid.
- burlesona 6y agoReally good video, thank you for sharing. This is definitely the kind of thing you want to see in motion, not just read about :)
- rkagerer 6y agoI'm confused by the reverse buoyancy. Is it from surface tension, air pressure, or something deeper?
