The effects of the ambient environment on the properties of a nanojet (NJ) injected into it are investigated using molecular dynamics (MD) simulations. These studies reveal that the ambient gas slows the propagation of the NJ. However, the intact-length of the NJ and the dynamics of droplet formation remain similar to the case of a nanojet propagating in vacuum. Separate MD simulations of a liquid nanobridge verify the exponent occurring in the description of the pinching dynamics of nanojets [1], predicted through analysis of the stochastic lubrication equations derived in ref. [2]. \\ $[1]$ J. Eggers, Phys. Rev. Lett. 89, 084502 (2002) \\ $[2]$ M. Moseler and U. Landman, Science 289, 1165 (2000)\\
