We study the problem of a 1 + 1 cord with a dynamical massless scalar field living in it, which separates a false vacuum and a conical region in a 2 + 1 space. A stable "particle-like" configuration can be found. Also, oscillating solutions exist which can tunnel to an expanding type solution. The most outstanding feature for these oscillating solution is that we do not need a singularity to create an infinite universe from them, and that an arbitrarily small tunneling is needed to achieve this. Possible consequences for similar processes, involving cosmic strings in 3 + 1 dimensions are discussed.
