The video shows a first-person view of a player in Minecraft placing red and black blocks in a specific pattern to create a contraption. The player places red blocks on the ground and on top of each other, followed by black blocks on top of the red blocks. The player then places redstone blocks on top of the black blocks and activates the contraption, which causes the redstone blocks to light up and the black blocks to move. The player repeats this process several times, creating a long contraption that moves the black blocks back and forth. The player then activates the contraption again, causing the black blocks to move in a continuous loop.
