We present in this fluid dynamics video a novel experimental setup with self-propelled swimmers on a free surface. The swimmers, modeled as flexible thin filaments, are subjected to external electromagnetic forcing driving a propagating elastic wave that gives rise to self-propulsion. The fluid-structure interaction problem of these passive anguilliform swimmers is analyzed in:
