The interstellar medium is constantly subjected to explosive accelerations from a variety of events ranging from stellar winds to supernovae. The kinetic energy imparted to the gas acts to counteract the gravitational force and modulates the rate of star formation. In this talk I will discuss how this large scale motion is changed into small scale random motions through shock instabilities and the implications for the dynamics of the interstellar medium.
