Nope, solid plastic; and can be dropped into fluids to test motion theory....

not at all. The 150 year old theory by Brit mathmetician focuses on drag coefficients in a viscous fluid.

What is the working principle of viscometer?
Image result for viscometer
These viscometers use the principle of 'rotational viscometry', i.e. their measurement of product viscosity is based upon immersing a specifically selected spindle within a sample of the product followed by measurement of the torque required to rotate the spindle at a set speed whilst immersed within the product sample ...
You're getting there; but this is
not a measuring device; more a visual device. Here's another view:

/\ nope! A project of Lord Kelvin indeed; but one that didn't use electricity, and was unsuccessful. The spherical bladed object was intended to move in a certain fashion as it descended through a fluid filled tubular container.

no machinery involved; just drop it in viscous fluid and observe the motion...if any, chiral interaction with fluid; as proposed in 1871
