In the video, a person is playing Minecraft. The player is standing in a grassy area with trees in the background. The player is holding a block of iron in their hand and places it on a white platform. The player then places another block of iron on top of the first one. The player repeats this process several times, placing blocks of iron on top of each other to create a tall stack. The player's health and inventory are visible at the bottom of the screen.
