Movie 1
Tandem locomotion: Two droplets with R1 = 0.1, R2 = 100, S1 = S2 = 1, 𝜆1 =𝜆2 =1. Initial angle Θ0 =0 and separation 𝑑0 =6
Movie 2
The chase: attraction-repulsion leading to indefinite separation with decreasing velocity.R1 =0.1,R2 =100,S1 =S2 =1,𝜆1 =𝜆2 =1, corresponding to Φ<1. Initial angle Θ=10 deg <Θ𝑐 and separation 𝑑=6
Movie 3
Repulsion-attraction leading to contact R1 = 0.1, R2 = 100, S1 = S2 = 1, 𝜆1 = 𝜆2 = 1, ,corresponding to Φ < 1, initial angle Θ = 10 deg< Θ𝑐 and separation 𝑑 = 4
