1) A nice Galileo thermometer with barometer funtion.
    2) In the Galileo thermometer, the glass ball with the same weight and size sink when temperature rises, and they          ascend when temperature falls.
    3) The glass balls differ in weight and the density of the liquid means the lowest of the floating ball in the upper part          of the cylinder shows the accurate temperature.
    4) Barometer can forcast the weather changes through the air pressure.
    5) A special wooden base to be a gift for office display.
