Movie S2. Alternating loops: Pattern of alternating loops obtained when depositing the same rod used in Movie S1 and from the same height, but at a higher value of the control parameter, ϵ=0.5 (injection speed, v=2.0 cm/s, and belt speed, v=1.0 cm/s). Experiments (Left) vs. simulations (Right) are shown. The movie is sped up by a factor of 5, with respect to real time.
