There is an electrostatic pressure acting on any charged conductor. This effect can be visualized by charging up soap bubbles: the additional electrostatic pressure eventually causes them to expand

 

The electrostatic pressure can also be written

\begin{displaymath} p = \frac{\epsilon_0}{2}  E^2, \end{displaymath}
