Figure 6.

(a) Scatter plot of the radii of a NaAlg aqueous droplet $r_{\mathrm{NaAlg}}$ and a ${\mathrm{CaCl}}_2$ emulsion rCaCl₂ measured before fusion. (b) Scatter plot of the radii of a fused droplet $r_{\mathrm{F}}$ and the corresponding prefused ${\mathrm{CaCl}}_2$ emulsion $r_{\mathrm{CaCl}}2$. The shape of a fused droplet is indicated by circles (front–back symmetric) or triangles (front–back asymmetric). Color code indicates the asymmetry index A. Only the data points for which the droplet fusion occurred are plotted.
