Our distinctive ornamental (but functional) thermometers utilise 17th century astronomer Galileo Galilei's discovery that the density of liquids varies with temperature. Carefully weighted glass globes are suspended in a liquid-filled tube, where they sedately sink or float as the surrounding air gets hotter or colder. Temperature is indicated by the engraved brass tag on the lowest floating globe. 11 globe models are 24" tall, seven globe models are 17" tall, five globe models are 13 " tall and Piccolo models (five globes) are 11" tall. Temperature is shown in Celsius.

Atmospheric pressure? Temperature? Electrical disturbances? The simple fact is, no one is quite sure how a storm bottle works. Or indeed how accurate it is. Nevertheless aboard HMS Beagle during the Darwin Expeditions of 1831-36 Captain Robert Fitzroy developed and refined the storm bottle (invented in the mid 18th century) and suggested that changes in crystal formation could be used to predict quite subtle changes in the weather. Measurements: 18x6”
