Lubricity is a major factor in engineering, architecture and life sciences. If materials are too slippery, or if an unknown factor enters a project and introduces a lubricitous factor of unknown magnitude, it can severely compromise the overall superstructure and delay completion of the project. Buildings have been known to slip and slide apart due to an unforeseen lubricity vector. The Dongle-Bromm Lubricity Scale was developed in the early 1790s by a team of scientists at the University of Pennsylvania. The Dongle-Bromm functions much like a pH scale; when the Dongle-Bromm scale is assembled and fully functional, one can simply place a sample on one of the reactor pads and apply light pressure. The apparatus will then supply a metrical analysis of its lubricity and create an automated printout. We have included a more practical home version of the Dongle-Bromm scale here; users will find it easy to compare the lubricity vectors of samples from around the home and workplace, including food and beverages, glue, liquid, soil, and clothing.
