Use water or glycerin as a lubricant at the end of the glass tubing before inserting it into the rubber stopper. ask teacher for proper lubricant. Protect hands and fingers by wearing leather gloves or placing a folded cloth between your hands and the tubing. hold it as close as possible to the part it is inserted to the rubber stopper. always point the tubing away from the palm of your hand that holds the stopper. use a twisting motion and push the tubing into the stopper. At the end of the experiment put on leather gloves or place the folded cloth between your hands and the tubing and remover the stoppers from the tubing to keep them from sticking to the glass. if it wont budge, use lubricant.
