The Tempo Drop is an elegantly simple device for weather prediction, using a mixture of water, ethanol, and camphor sealed in a crystal teardrop. As a modern version of a storm glass, the forecaster makes for an infinitely more romantic approach to checking the weather than an app.
Indeed, reading the tempo drop is a sophisticated art in itself. At its basic function, clear glass means clear skies, while a cloudy horizon will be anticipated in the hazing of the liquid within the drop. With practice, some notice even more finely detailed prognostication: the appearance of tiny crystal stars within the liquid heralds an approaching thunderstorm or snow storm; while thready formations at the top of the liquid suggest wind. Rousing the senses to concentrate and focus in meditation, Tempo Drop prompts the user to get to know its patterns.
The design in itself has been around for centuries with shipping records reporting of their usage dating back to Admiral Robert FitzRoy, who invented the device for his voyage with Charles Darwin on the HMS Beagle. And yes, Charles Darwin credited most of his training in natural history to his time spent on the Beagle. Though scientists have no conclusive answer on how the liquids are able to react based on weather conditions, theories include electromagnetic changes, temperature changes and particles quantum tunneling through the glass. And, as with any forecasting system, predictions offer a rough indication of weather conditions.
These pieces hearken back to a time of Benjamin Franklin and Nikola Tesla, when humans used their cleverness for much more than just building circuitry. With its chic design, the Tempo Drop would be equally at home in a modern loft, a Victorian cottage or a Steampunk laboratory straight out of a Marc Caro and Jean-Pierre Jeunet film. Despite functionality, at the very least, the instrument offers a unique focal point for meditation and a fun conversation piece.
