Galileo Thermometer 44cm

Sold out

This beautiful sealed glass container contains colourful, carefully weighted baubles of hand-blown glass. As the ambient temperature changes, the paraffin within the thermometer changes density, affecting which baubles float and which sink. This property was first observed by Galileo, and these thermometers have been named in his honor. By observing which bauble is floating in the middle of the column, or by averaging the ones bracketing the gap (if there is no ball in the middle), the temperature can be read. This model is accurate between 16°C and 34°C and is 44cm tall. This makes for the best gift for lovers of science and/or Galileo! Best suited for older children and adults.
