As shown in \textbf{Figure 3} in this phenomenon, Bouncing Jet, bath velocity and the jet velocity are two significant parameters that makes changes in the behavior of the bouncing. If the bath velocity is too small, then the bouncing portion of the liquid may collide with the falling stream . Therefore, in order to get stable bounce, the bath velocity has to be fast enough. As bath velocity increases, the jet gets more horizontal momentum and the rebound becomes more oblique. As mentioned above, during the bouncing, it creates a layer of air (also called air sheath) between the bath and impinging jet. Researchers have added laser beam to travel along the jet and measured the thickness of the air layer that is about several micro meters. Im going to move this to other spot  The equation relating these is: \begin{equation} \frac{4\pi \mu {V_{bath}}^{2} L^{2}}{V_{jet} ln{\frac{7.4}{Re_{bath}}}}\approx \sigma b^{2}Q^{2} \end {equation}  Where Q is the volumetric flow rate into the basin, \mu is the coefficient of friction, Re is the Reynolds number, \sigma is surface tension, b is the length scale's slope, L is the length of the bounce and V is velocity of the respective fluids. Thus the length can be increased by increasing either Q or V_{bath} and decreased with V_{jet} and altering the flow of the bath (4).
