to keep the KN clouds confined. These values are in general agreement with Chevance et al. (2016), who report that the stapler nebula is located in a region with gas pressure $\sim$ 0.85-1.2$\times 10^6$cm$^{-3}$K, with the peak found in KN2 (see Fig. 15 in Chevance et al. 2016).

### Variation in properties as a function of distance from R136

The $V_{\rm lsr}$, and $M_{{\rm H}_2}$ of each cloud are plotted as a function of projected distance from R136 in Fig.\[fig:distanced\]. The velocity of the clouds increases as a function of projected distance from R136. The velocity of the KN3 cloud loosely matches the radial velocities of the stars within R136[^2]. The KN1 cloud is closest in projection to R136 and is blue shifted with respect to the mean velocity of stars in the cluster. This suggests the KN1 cloud, (and likely KN2 and KN3 clouds as suggested by the lack of background stars) lie slightly in front of the cluster. The clouds appear to be moving away from the cluster as function of projected distance from it (Fig.\[fig:distanced\]a).

The $M_{{\rm H}_2}$ of each cloud also increases as the projected distance from R136 increases (Fig.\[fig:distanced\]b). The KN1 cloud mass is approximately
