Our colourful glass thermometer is based on Galileo's theory: in liquid, a body of fixed mass becomes less buoyant as the liquid temperature rises, and more buoyant as the temperature decreases—due to changes in liquid density. As the temperature changes, the multicoloured balls rise and fall within the liquid-filled thermostatic tube. The lowest sphere in the top group within the instrument indicates ambient temperature. Made of glass, measures 23cm tall with five temperature indicators.

Invented in the 19th century by Admiral FitzRoy, the famous sailor and meteorologist, this amazing and mysterious liquid and crystal filled storm glass device is used for predicting the weather up to 2 days in advance. You'll see changes in the crystal formations if it will be fair weather (clear liquid), rainy weather (murky liquid), thunderstorms (crystals at the top), cloudy skies with snow (large flaky crystals) and even windy weather (threads of crystals). A wonderfully simple antique reproduction with an elegant wooden base. Measures 17cm tall.

This durable steel weather station has everything you need to keep track of what mother nature is up to. The acrylic rain gauge accurately measures rainfall, the thermometer tells you the temperature in Fahrenheit and centigrade, and the weather vane and spinner tracks the wind direction and indicates the relative wind velocity. Durable steel construction coated with black enamel for years of enjoyment during sunshine, rain, sleet, snow and wind. Garden Weather Station measures 138cm tall and includes a 15cm forked stake to adhere to the ground.Minor assembly required. Instructions included.

This thermometer is based on a scientific principal discovered by Galileo. As the liquids in the cylinder contract at higher temperatures, the spheres of slightly different weights rise; as the liquids cool, the spheres drop. The lowest floating sphere in the upper part of the cylinder tells the correct temperature. Fahrenheit on one side of the hanging plaques, centigrade on the reverse. Made of glass, it's an attractive and fascinating way to measure the temperature of your home. Measures 43cm tall x 8cm in diameter.
