One last factor determining accuracy is how the spheres are calibrated. In this case, you'll need to take the average value between the lowest bulb's temperature in the top group and the highest sphere in the bottom group (the spheres directly above and below the gap). The buoyancy principle states that objects with a greater density than their surroundings sink and objects with a lesser density than their surroundings will float. Changing temperatures cause the colorful orbs to either sink or float inside the glass tube. This image may not be used by other entities without the express written consent of wikiHow, Inc.
