Disappearing Boat

Disappearing Boat
The footage from this video was recorded the late 50's. It starts by showing a ship floating on the water. An explosion occurs underwater in the background, and a massive wave is created. Near the end, as the boat is beginning to get submerged by the water, the man from the London Dungeon video pops up screaming "YEAAAH!" and falls down.
