Mercury 
Owing to its acoustic properties, mercury was used as the propagation medium in delay line memory devices used in early digital computers of the mid-20th century.
Ring modulation is a signal-processing function, an implementation of frequency mixing, performed by multiplying two signals, where one is typically a sine wave or another simple waveform and the other is the signal to be modulated
Resonance frequency
The frequency at which the ceramic element vibrates most readily, and most efficiently converts the electrical energy input into mechanical energy, is the resonance frequency.
 Ice-nine is described as a polymorph of water which instead of melting at 0 °C (32 °F), melts at 45.8 °C (114.4 °F). When ice-nine comes into contact with liquid water below 45.8 °C, it acts as a seed crystal and causes the solidification of the entire body of water, which quickly crystallizes as more ice-nine.
Intra-action understands agency as not an inherent property of an individual or human to be exercised, but as a dynamism of forces (Barad, 2007, p. 141) in which all designated 'things' are constantly exchanging and diffracting, influencing and working inseparably
Lightening

[BodyNoise Amp] is an electronic circuit that generates sound through contact between bodies.
[BodyNoise Amp] is an amp based on LM386 chip. This device transforms body electrical activity in sound by contact between different bodies. [BN A] allows to experiment a tact / sound cyborg synesthesia and the perceptive and identity deconstruction generated by this one

{title} Electromagic Fog
 
During Electromagic Fog activation, trans-universal constellation bolwerK will combine parascientific history, anthropology, and technology to introduce participants to the electromagnetic spectrum and how radio and farming metaphors intertwine. During this open lab, participants grow crystals and experiment with their physical, acoustic, electrical, and electromagnetic properties, transmitting and receiving signals from the body to the mind and intra-acting frequencies. 
 
Hosted by Marthe Van Dessel and electronic musician Yasi Perera.

{intertwinement farming - radio transmission}

 Broadcasting refers etymologically to a sowing technique—scattering seeds—not one-to-many spreading seeds of information but circulating locally, in terms of circuits and citizens being present in the (Hertzian) waves
"Ann Friz"

Propagating: creating new plants from seeds, cuttings, bulbs…, is a term used for how radio waves travel from one point to another, by the sun and the reflection on the ionosphere.

{recipe - ingredients + tools }

cream of tartare 100g
demineralized water 125 ml
sodium carbonate 23g

Reaction
mix cream of tartare & distilled water, heat the solution till 70°
add sodium carbonate little by little to trigger the chemical reaction
chill reaction in plastic container to 5,5°  + desiccant.   use fridge over night, or freezer with thermometer
make climate controlled dry chamber. Do it over 3-4 days. crystals should grow. 

Purification 
wen you have crystal solids. wash in a mesh strainer with purified water (most clean water you can get) 

Seeding
keep a few seed crystals.  suspend each one from stick with nylon wire in a paper cup

Redissolving
add crystals gradually to hot water (21,1-32,2 °) not boiling. dissolve
add crystals until you put one in that won't dissolve. 
pour off saturated crystal liquid into plastic container. leave solids 
add seed crystal into container and let it all evaporate. 
crystal will grow monocrystaline *
