Project CLAMP?
Trump's wall construction video: https://twitter.com/realDonaldTrump/status/1098295228837048325
See that spray-painted sign in the lower left? CLAMP?
We know “The Wall” refers to a system that protects us in all dimensions. I think of it as our protective shield in the frequency wars. Maybe it's not all at the USA-Mexico border. But as for the portion that IS at the USA-Mexico border:
Is it an antenna? A resonance clamp? An Active Clamp Circuit? Are the vertical steel tubes Resonance tubes?
For orgonefags, who are familiar with cloudbusters in the orgonite arena, do the vertical sections work like wave guides?
Sections of the wall are different from location to location. Why is that thick horizontal plate attached across the top in El Paso, but not in Calexico?

Vinyl sound can be significantly improved when unwanted resonances between record and platter can be reduced. And Clamp-it is the solution. You can fine-adjust pressure according to condition of your warped records and fitting the Clamp-it is easily done within seconds. This accessory will please your ears and its beautifully machined diamond-cut edges will look extremely cool on any turntable!

Let your class measure the velocity of sound in air! After partially filling the resonance tube with water, sound a tuning fork of known frequency at the tube’s open upper end. Then the water level can be adjusted until the air in the tube resonates at the same frequency as the tuning fork, increasing the volume of the sound. The apparatus consists of a water reservoir, glass resonance tube marked in increments of 1mm, a support stand and two clamps to hold the tube in position.
