Galileo thermometer

Galileo thermometer is a simple and accurate thermometer,now it mainly used as decorations. Galileo thermometer consists of a full of water and several floating bubbles of glass composition.These bubbles are filled with colored liquid mixture of glass balls.Each glass bulb temperature with a small metal label instructions connected.Engraved with a number on the label and temperature sign.In fact,these metal tags are calibrated balance of things.The weight of each tag is slightly different with the other.Because these are hand-blown glass bulbs made,their size and shape are not the same.The glass bulb by adding a certain amount to which the liquid to make it exactly the same way that the density calibration.Thus,in connection with re-tag after,each glass bubble density (mass volume ratio) and other glass bubbles are slightly different,All glass bulbs are very close to the density of water around their density.Galileo thermometer is a basic principle of the thermometer as the outdoor air temperature around the glass-bulb temperature of the water will change.With the changes in water temperature,water will expand or shrink,its density is thus changed.So,at any given density,some bubbles will be floating on the sea to the glass,while others will sink.Sinking up to the glass bubble that is about the temperature of the current instruction.

1)it is a hand-crafted
2)can measure temperature
3)as a concept or decorative gifts
4)size:many sizes for your choice
