The video shows a first-person view of a player in Minecraft. The player is standing on a grassy terrain with a few structures in the background. The player is holding a bucket and begins to place water on the ground, creating a small puddle. The player then places a blue block on top of the puddle, which causes the water to spread out and create a larger puddle. The player repeats this process several times, placing blue blocks on top of the water and causing it to spread out even more. The player then places a red block on top of the water, which causes the water to spread out even further. The player continues to place blue blocks on top of the water, creating a large blue puddle on the grassy terrain.
