Yes, the molecules do move. Although you can't tell, they are always moving. This is because the molecules have little energy. When they have little energy, they move slower. I hope this helps! :)
molecules in all thing move weather it be a solid or a liquid. the molecules in a liquid are far apart and move slow. the molecules in a solid are tightly packed and continuously vibrate. you can put your hand through water but you cannot put your hand through a steel beam.
