The video is a screen recording of a Minecraft game. The player is in a desert biome, and the player is placing TNT blocks on top of each other to create a tower. The player then places a water bucket under the tower and detonates the TNT, causing the water to spread out and create a small pool. The player then places more TNT blocks on top of the water and detonates them, creating a larger explosion and spreading the water even further. The player repeats this process several times, creating a large explosion and spreading water across the desert biome.
