Heating a Liquid in a Test Tube
Clip the holder near the mouth of the tube and keep the tube tilted, with its open end pointing away from yourself and others. Warm it just below the surface of the liquid and move it gently in and out of the flame; heating only the bottom can make the liquid boil suddenly and spurt out.
Wood conducts heat slowly, so the handle stays comfortable to hold, but keep the holder itself out of the flame.
