Acoustic Levitation in ULTRA SLOW MOTION - Smarter Every Day 134

There are plenty of videos that do so with talc and paint. R. Watson Watt did it with aeroplanes. But I think he was cheating ;~)

I have a difficult one for you I can't prove this is not just coincidence but when a weather system steps off the Eastern coast of North America A significant earthquake occurs in the Aleutians. This has a reciprocal that before a weather system arises a seiche is initiated in the ocean in which the next tropical storm will occur. The epicentre will be in the region where the storm peaks and lie on the storm track. As proof of this two or three related earthquakes always occur with the demise and a blocking Low will contain two or three parallel fronts. I only know for sure they occur with the North Atlantic but am pretty sure they do the same with the North Pacific. Could you twist the arm of some seismologist to see if they can follow this idea with whatever is required.

You get it

ENJOYED IT. KEEP UP GREAT WORK!

Really, really cool. This is a GREAT way of visualizing something that radio operators have to consider every day: VSWR (Voltage Standing Wave Ratio). With VSWR you're dealing with RF frequencies that are reflected back at a transmitter due to an impedance mismatch on an antenna at the end of a feed line. So instead of the power that should be going to your antenna that power (or some portion of it) comes right back at you, creating standing waves on the feed line like you see here in the video. Since AC power (really any frequency) can be shown as a vector, you can "do math" on them. In this scenario, you've got nulls in between two opposing vectors that are *in phase* and the peaks and valleys are added together and grow accordingly. In the radio world, you're dealing with kilo-volts being sent down a coax feed line and if you send down a kilovolt and let's say, 70% of that power is reflected back to you in-phase, those spikes can exceed the voltage rating of a cable. So instead of a drop of water exploding as in your video, this voltage spike can burn through your coax, cause fires, damage equipment, and otherwise ruin your day.

Awesome vid and love my 2 Ford's!

Exploding frisbees of water!

Very cool video. Loves those explosions.

this is really cool. could you move the drops up and down changing the phase of one the signals. ? I would think you could, as that would move the position of the standing waves. also wat was the amplitude of that signal ?

Damn that just made my day. Will the footage that appears in American Idol also be posted to Patreon?

That's awesome!! I cant wait for you to post it on Facebook so I can share it. :-)

Really! Really! Great video. Second only to your old "Godzilla for Hire" series. BTW you still owe the internet a new episode.
