Tubing Tube

why should the delivery tube be removed first from the lime water before the flame is put off?
Well, the procedure follows:
-2 grams of PREVIOUSLY HEATED CuO and a corn-grain amount of sugar were grinded in a mortar.
-The mixture was transferred in a test tube and covered with a rubber stopper with bent glass tubing.
-The test tube was attached to an iron stand in an inclined position, and the other end of the glass tubing was immersed in 5ml Lime water.
-The test tube with the grinded mixture was heated with a bunsen burner.
when it cools it will suck the fluid back up the tube
