We report number density-dependent motion of many-body system of self-propelled ion gels on the water surface. ion gels (n = 3, 10, 25, 50, 100) were introduced to petri dish with different Φ (Φ=50, 65, 100 mm). Initially, ion gels moved and collided, and they formed aggregates over time when number density of many-body system was over 1.00 /cm².
