Get the benefit of two historical meteorological devices – a storm glass and a Galileo thermometer – in one with this fascinating piece of equipment which will delight anyone interested in the weather. You’ll never get caught out without an umbrella again.
Watch: How a storm glass can predict the weather. This sealed glass device contains chemicals that crystalise in such a way as to indicate what’s in store for weather watchers a couple of days in advance. Instructions are included so you can learn to ‘read’ your storm glass.
Learn: All about Galileo who, in 1593, discovered that the density of liquids reacts predictably to changes in temperature leading to the invention of his eponymous thermometer. The Galileo thermometer can measure between 16-32⁰C.
Discover: How the Galileo thermometer works. The sealed glass cylinder contains five floating glass bulbs. Each bulb has a calibrated, weighted metal tag. The temperature is determined by the lowest floating bulb. When there is a bulb in the middle, the temperature should be read as between this degree and the lowest floating bulb.
Best for: Meterologists, big or not-so-big, who enjoy watching weather systems on the move.
Keep storm glass and Galileo thermometer out of reach of children.
Contents can be fatal to children if sucked or swallowed. Avoid contact with eyes.
