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 contraption. The contraption appears to be a launcher or cannon made out of redstone blocks and a lever. The player is seen placing the blocks in a precise manner, with the lever being placed at the end of the contraption. The player then activates the lever, causing the contraption to launch a projectile into the air. The video is shot in a desert biome, and the player's inventory is visible at the bottom of the screen.
