This has got to be one of the coolest things I've ever seen!

Thanks for this! --- I've been meaning to 'play around' with this phenomenon but never find the time...

FWIW I recall a PBS special (I know...:oops:) wherein an Egyptologist hypothesized that the Great Pyramid was stacked via this method (let's see: technology too primitive for cranes but contemporaneous with drivers/transducers capable of many tens of kPa overpressure? -- Go figure:rolleyes:)

Best regards

That is as likely as a great flood causing rocks to erode into cubes and naturally stacking themselves into a pyramid as the fluidized solids settle.
