In the video, a person is seen building a structure using blue and purple blocks. The person is carefully placing each block on top of each other, creating a tower-like structure. The structure appears to be made of plastic blocks, and the person is using a variety of different shaped blocks to build it. The person's hands are visible as they work on the structure, and they seem to be focused on their task. The background is blurred, but it appears to be a room with a table and other objects.
