In the video, we see a first-person view of a player in the game Minecraft. The player is standing on a sand block and is surrounded by water. The player then places a bucket on the sand block and begins to dig down into the sand. As the player digs, the water level rises, and the player continues to dig until the water level reaches the sand block. The player then places a bucket on the sand block again and begins to dig upwards, causing the water level to fall. The player repeats this process several times, digging down and up in the sand block, causing the water level to fluctuate. The video ends with the player looking down at the sand block with water surrounding it.
