  For more than a century, the consensus has been that the thin-film hydraulic
jump that can be seen in kitchen sinks is created by gravity. However, we
recently reported that these jumps are created by surface tension, and gravity
does not play a significant role. In this paper, {we present experimental data
for hydraulic jump experiments conducted in a micro-gravity environment
($\approx 2\%$ of Earth's gravity) (Avedisian \& Zhao 2000; Painter et al.
2007; Phillips et al. 2008). The existence of a hydraulic jump in micro-gravity
unequivocally confirms that gravity is not the principal force causing the
formation of the kitchen sink hydraulic jump.} We also present thirteen sets of
experimental data conducted under terrestrial gravity reported in the
literature for jumps in the steady-state for a range of liquids with different
physical parameters, flow rates and experimental conditions. There is good
agreement with {Bhagat et al.}'s theoretical predictions. We also show that
beyond a critical flow rate, $Q_C^* \propto \gamma^2 /\nu \rho^2 g$, gravity
does influence the hydraulic jumps. At lower flow rates, at the scale of the
kitchen sink, surface tension is the dominating force. We discuss previously
reported phenomenological and predictive models of hydraulic jumps and show
that the phenomenological model -- effectively a statement of continuity of
radial momentum across the jump -- does not allow the mechanism of the origin
of the jump to be identified. However, combining the phenomenological model and
{Bhagat et al.}'s theory allows us to predict the height of the jump.
