The video shows a first-person view of a player in a game, where the player is building a structure using blocks. The player places a glass block on top of a purple block, and then breaks the glass block, causing the purple block to fall. The player then places another glass block on top of the purple block and breaks it again, repeating this process several times. The player's inventory is visible at the bottom of the screen, showing various blocks and items available for use.
