Galileo Thermometer

After the testing of my galileo thermometer and nothing going wrong with the bulbs being boiled, I went ahead and ordered bulbs to be made by Scott Glass. These are the bulbs I got back.


The bulb has washers hanging from it giving it a total weight of 12.4 grams with a diameter of 30 mm and wall thickness of 0.3mm (these are rough sizes)
With these sizes and weight the bulb would sink and boiling and float a around 84 C
