The ancient Catholic Church derided Galileo as a heretic simply because his scientific line of thinking did not concur with what the Church thought, but bring home a piece of the legend today in the form of the Galileo Thermometer. What makes the Galileo Thermometer different from the rest as it comes in the form of a single floating disk, encased between a couple of glass panes in the process. It doesn’t matter which continent you live on, since the temperature reading is available in both Fahrenheit and Celsius readings, making this one decent desk accessory or functional decoration for your home or office.
