In the video, a person is seen using a ruler to measure the distance between two hexagonal red objects placed on a wooden surface. The person then places a small Lego figure on the ruler and adjusts its position to ensure accurate measurement. The person's hands are visible as they manipulate the objects and the ruler. The ruler is yellow with black markings, and the Lego figure is blue with a red cap. The hexagonal objects are red with a flat surface and sharp edges. The wooden surface has a light brown color with visible wood grain.
