A Variety of Vessels

                 People use the many different types of glass to make scientific instruments.
              One of the most common instruments is the test tube.  It is a long, narrow
              container made of thin glass.  It is used to heat and store liquids.  Beakers
              are larger containers that can stand on their own.  They have wide openings
              and small spouts for pouring.  Funnels are pipes with wide necks and narrow
              stems.  They are used to channel liquids into vessels with small openings.
              Flasks have large bases and small necks.  Substances are often heated in flasks.
              A Fleaker® is a combination of a flask and a beaker!

                          Dolly the sheep began her
                          life in a glass test tube
                          in 1996.  She was the first
                          cloned mammal ever to be
         18               created from an adult cell.
