chemist with test tube
A test tube, filled with reagents, in the process of being heated, to bring about reaction.
In chemistry, test tube is cylindrical finger-like length of laboratory glassware, open at the top, usually with a rounded U-shaped bottom, used by chemists to hold, mix, or heat small quantities of solid or liquid chemicals, especially for qualitative experiments and assays.

Social test tubes
See main: Social test tube; Social retort
A "social test tube" is a conceptual extrapolation of the laboratory size test tube up to the social level of experimental reactions occurring between people.

The following is the conceptualization of the bringing of the Captain (C) to the system of the estate to visit with he (B) and his wife Charlotte (A), from P1:C2 of German polyintellect Johann Goethe’s 1809 physical chemistry based novella Elective Affinities:

I wonder what would happen if

The following is a 2013 chemical analogy type sketch of a social beaker by Ben Biddle in a blog entitled “Innovation is like a Chemical Reaction”, the coffee napkin sketch representative of what he calls a “powerful analogy for innovation”, which he describes as follows: “catalysts are problems in need of a solution. Adding heat means tapping into the passion of the individuals working on the problem. Increasing the surface area amounts to opening up your organization and exposing it to more ideas. Motion comes from changing the context – just mentally re-framing things in a new way or even physically moving your location, as you might do with an offsite. When they all come together, there’s a transformative reaction.” (Ѻ)

chemical analogy

The following diagram, below left, shows a test tube version different types of chemical men (Ѻ) and chemical woman (Ѻ) in test tubes, conceptualized as different types of reactants that would react differently with each other when mixed to form products (single individuals + dihumanide molecules + other variants).
Men + Women = Reactions (test tube)
A test tube rendition of mixing different men with different women, as reactants, and forming the products of single human molecules, couples (dihumanide molecules), and other intermediates such as the gay molecule, lesbian molecule, polygamous molecule, in Christopher Hirata terminology.

Quotes
The following are related quotes:

“Hence it is that we can have no precise laws in history as we have precise laws in physics, chemistry and mathematics; that history can never be a science in that highly rigid sense … the chemist, for example, can boast a superior apparatus for ascertaining the truth. In formulating the laws which govern an element, he can repeat his experiments thousands of times with all the factors precisely the same, or with endless variations of factors. The historian has no control of phenomena in the blowpipe (Ѻ) or test tube sense.”
— Allan Nevins (1938), The Gateway to History [1]

“You can’t put an omnipotent deity in a test tube.”
Eugenie Scott (1994), “Keep Science Free From Creationism”; cited by Lee Strobel, 2004 [4]

“People are like particles, they behave in groups as if they were molecules in a test-tube.”
Forbes Allan (1999), Milton’s Progress [2]

Ecological stoichiometry [is about] how chemical elements come together to form evolved, living species in ecosystems. Organisms can be thought of as complex evolved chemical substances that interact with each other and the abiotic world in a way that resembles a complex, composite, chemical reaction. Like any other normal chemical rearrangement at the surface of the earth, when organisms interact, mass must be conserved and elements are neither created nor destroyed. There is stoichiometry in ecology, just as there is in organic synthesis in a test tube”.
Robert Sterner and James Elser (2002), Ecological Stoichiometry [3]
