The video begins with a pile of colorful building blocks scattered on a white surface. The blocks are then carefully arranged in a pyramid shape, with each layer decreasing in size from the bottom to the top. The pyramid is made up of blocks in various colors, including red, blue, green, yellow, and orange. The video shows the pyramid from different angles, highlighting the symmetry and precision of the arrangement. The pyramid is then labeled with numbers from 1 to 25, indicating the number of blocks in each layer. Finally, the pyramid is dismantled, with the blocks falling away from the structure, leaving a blank white surface.
