The video shows a close-up of a small brown insect with long antennae and legs, swimming in a clear glass container filled with water. The insect moves slowly and gracefully, occasionally changing direction. The container appears to be placed on a surface with a blue light source reflecting off the water's surface. The insect's movements create ripples and waves in the water, and its body is partially submerged. The video captures the insect's actions and movements in detail, highlighting its delicate features and the clarity of the water.
