Heating Liquids in the 20 x 180 mm Tube
Fill the tube no more than about a third full, grip it near the mouth in a test tube holder and tilt it so the open end points away from everyone. Warm it gently, moving it through the flame and heating just below the liquid surface, so the contents do not bump out.
