The video shows a first-person view of a player in the game Minecraft. The player is standing on a sandy beach next to a body of water. The player is holding a bucket in their inventory and is using it to fill a glass block with water. The glass block is transparent and is placed on the sand. The player then places another glass block on top of the first one, creating a stack of two glass blocks. The player then uses the bucket to pour water into the top glass block, causing it to flow through the bottom glass block and back into the water. The player repeats this process several times, creating a waterfall effect. The video is shot during the daytime in the game, and the sky is clear and blue.
