The video shows a first-person view of a player in a Minecraft game. The player is placing blocks in a specific pattern to create a doorway. The blocks used are slime blocks and sticky pistons. The player places the slime blocks on the ground and then attaches sticky pistons to the sides of the slime blocks. The player then activates the pistons, which push the slime blocks upwards, creating a doorway. The video is shot in a virtual environment with a clear sky and white ground.
