Product Description

This attractive set features a Galileo thermometer, which reads 64-80 degrees F. When the temperature rises, the liquid inside the glass tube becomes less dense and the liquid-filled bulbs sink. When the temperature cools, the process is reversed and the bulbs rise from the bottom. -- Variations in barometric pressure associated with weather systems are immediately revealed by the water level in the spout of the glass barometer globe printed with a frosted world map. A low level of liquid in the spout indicates high-pressure and fair weather can be expected. A high water level is associated with bad weather. -- In cases of severe weather and major storms, the water may even run out of the spout. Both the thermometer and the globe are mounted on a sturdy wooden base.

From the manufacturer

Glass Galileo Thermometer with Globe Storm Glass

For hundreds of years, the Galileo Thermometer with Glass Barometer have offered function and timeless beauty. To this day, they remain a distinctive decorative accent for any home or office.

A decorative thermometer that really works.

Galileo Thermometer Background

The Galileo Thermometer works on principles developed by Galileo Galilei (1564-1642), the pioneer of modern astronomy and physics. Through his experiments, Galileo discovered that liquids change density as the temperature increases or decreases.

Galileo Thermometer

How it Works

A large glass tube is filled with clear liquid. Floating inside the tube are five small glass bulbs. The bulbs are calibrated by filling them with precise amounts of colored liquid so that they have a specific density relative to the clear liquid in the main tube (some bulbs are calibrated to be higher in density and some are lower). Finally, metal tags that serve as counter weights are hung from each bulb. A temperature is engraved on each tag.

When temperature rises, the liquid inside the glass thermometer tube becomes less dense and the liquid-filled bulbs will sink. When the temperature drops, the liquid inside the tube becomes denser and the liquid-filled bulbs will float. Since the bulbs are different density, some will sink or float more than others.

Storm Glass Barometer Background

The Storm Glass Barometer also works on principles developed during Galileo’s time. Attempts to solve problems with water pumps led to experiments by scientists such as Gasparo Berti and Evangelista Torricelli. These experiments unintentionally resulted in an effective instrument to gauge atmospheric pressure, and in turn, the weather.

Storm Glass Barometer

How it Works

Atmospheric pressure exerts force down the barometer’s glass spout, affecting the liquid level inside the barometer’s globe.

Reading a Galileo Thermometer and Storm Glass Barometer is Part of the Fun!

It's not just a decorative thermometer, it actually works! Each bulb inside the Galileo Thermometer represents a temperature, as indicated by the metal hang tags beneath each bulb.

The temperature is determined by the lowest floating bulb in the thermometer.

When a bulb is seen floating in the middle of the tube, the temperature reading is between that bulb and the lowest floating bulb at the top of the tube.

If all the bulbs float to the top, the temperature is less than the lowest floating bulb.

If all the bulbs sink, the temperature is above the highest bulb.
