a rotameter consists of a tapered tube, typically made of glass with a 'float' a shaped weight, made either of anodized aluminum or a ceramic , inside that is pushed up by the drag force of the flow and pulled down by gravity. the drag force for a given fluid and float cross section is a function of flow speed squared only, see drag equation.
when a meteor strikes a planet's surface, the energy release from the impact can melt rock and soil into a liquid. if the liquid cools and hardens quickly into a solid, impact glass forms before the atoms have time to arrange into a crystal lattice. impact glass is dark brown, almost black, and partly transparent. known examples of impactite
a domestic ice cream maker is a machine used to make small quantities of ice cream for personal consumption. ice cream makers may prepare the mixture by employing the hand-cranking method or by employing an electric motor. the resulting preparation is often chilled through either pre-cooling the machine or by employing a machine that freezes the mixture.

the machines utilise the principles of a centrifuge to enhance the gravitational force experienced by feed particles to effect separation based on particle density. the key components of the unit are a cone shaped 'concentrate' bowl, rotated at high speed by an electric motor and a pressurized water jacket encompassing the bowl.
impactite or impact glass is rock created or modified by the impact of a meteorite. impactite includes shock-metamorphosed target rocks, melts suevites and mixtures of the two, as well as sedimentary rocks with significant impact-derived components shocked mineral grains, tektites, anomalous geochemical signatures, etc. .
