The video shows a group of people standing in front of a large tank filled with jellyfish. The jellyfish are floating around in the water, and the people are watching them. The tank is illuminated with a blue light, and the jellyfish are glowing in the dark. The people are silhouetted against the light, and their faces are not visible. The jellyfish are of various sizes and are moving slowly in the water. The tank appears to be in a public space, possibly an aquarium or museum.
