SUMMARY
The rods depicted in molecular models, such as those representing water, are not physical components of the molecules themselves but serve a purely illustrative purpose. According to Kristian Hermansen, these rods symbolize the chemical bonds formed by quantized electromagnetic forces between atoms, specifically hydrogen and oxygen in water. They are designed to represent the type and length of the bond rather than being actual structures observable under a microscope. Thus, the rods function as a utility to convey the concept of molecular attraction, akin to how a model might use a rod to connect an action figure to a globe to represent gravity.
