The video shows a person's hands holding a clear plastic object with a hole in the center. The person is using a white tube to apply a substance into the hole. The substance appears to be a clear liquid. The person's hands are steady, and they seem to be carefully applying the substance to ensure it fills the hole completely. The plastic object has a hexagonal shape, and the hole is located in the center of one of its faces. The background is blurred, but it appears to be a workshop or lab setting.
