Our goal is to help educate our customers in Martin, Palm Beach, St. Lucie and Indian River Counties in Florida about energy and home comfort issues (specific to HVAC systems). (LogOut/ Temperature changes affect the density of the outer clear liquid and this causes the bulbs to rise or sink accordingly. How much does a Galileo thermometer cost? 
3) Push the injection tube onto the syringe (shown below). They also tend to lack a range of temperatures most cover the temperatures from 68-84F degrees which makes them suitable only for heated/air conditioned indoor locations. Our list was compiled based on what led us to do so? So, at any given density, some of the bubbles will float and others will sink. The bubbles themselves, typically hand-blown glass, are each different in size and shape but theyre all calibrated so they have the same exact density. There is a higher chance it wont be reliable. So, after the weighted tags are attached to the bubbles, each differs very slightly in density (the ratio of mass to volume) from the other bubbles, and the density of all of them is very close to the density of the surrounding water. To read the temperature just look at the lowest ball that is floating.
