PRODUCT DETAILS
Description
A fascinating desk-top thermometer based upon the scientific principle expounded by Galileo Galilei (1564-1642), that the density of a liquid changes in proportion to its temperature. 5 weighted globes, each with temperature markers, are suspended inside the mineral oil-filled glass tube. As air temperature changes the globes rise and fall: the lowest floating globe indicating the temperature. This thermometer measures temperatures 18-26°C. If all the globes rise to the top it indicates the current temperature is below the temperature of the lowest floating globe. If all the globes sink this indicates a higher temperature than the highest floating globe.
