For organic and inorganic chemistry, this is the best available model for lecture and laboratory demonstration. The water molecule is 20" across with 2"-diam atom centers. Bonds and atom centers are color-coded. Single bonds are wooden; double bonds are flexible plastic. Female receptors for bonds are vinyl, which adheres to the bonds to hold the models together tightly.
