In this talk I will describe a recent experiment involving an uncommon realization of individual one-dimensional Bose gases (1DBGs) using a single high aspect-ratio dipole trap. While this realization aims to enable the study of multi-component, strongly interacting bosons in 1D, we start by fully characterizing the thermodynamic state of a much simpler, single-component, interacting 1DBG via its equation of state. We benchmark our measurement against the exactly known Yang-Yang thermodynamics and learn that even though our 1DBG undergoes evaporative cooling, it simultaneously escapes degeneracy. I shall discuss the prospects and challenges of future experiments in the context of these results.
