Extremely rare negative of the first seconds of the Baker atomic bomb exploding at Bikini Atoll. This is from one of the cameras that was set up to photograph the explosion and measures 7 5/8 by 9 15/16 inches. Marked Kodak Safety Film 113 with the dot between the s and a. Perfect condition other than the small pin hole in upper left corner as shown (looks like tack hole).The second test, codenamed BAKER, occurred at 8:35 AM local time on July 25 when an implosion-type bomb, suspended 90 feet underwater, exploded with a yield of 23 kilotons. The BAKER shot was the first underwater test of an atomic device, and the explosion produced so many unusual phenomena that a conference was held two months later to define new terms for use in descriptions and analysis.

The underwater fireball generated by the blast took the form of a rapidly expanding hot gas bubble, which reached the sea floor and the sea surface simultaneously. The result created a shallow crater on the seafloor 30 feet deep and nearly 2,000 feet wide. At the top, water burst through the surface like a geyser, creating a massive \"spray dome\" containing nearly two million tons of water. The expanding dome stretched into a hollow chimney of spray called the \"column,\" 6000 feet tall and 2000 feet wide with walls 300 feet thick.

The space vacated by the rising gas bubble caused a tsunami which generated a wave 94 feet high. By the time the wave reached Bikini Island beach 3.5 miles away, a series of nine 15-foot waves tossed landing craft onto the beach and filled them with sand. Ten seconds after the detonation, falling water from the column created a 900-foot \"base surge\" which rolled over many of the target ships, painting them with radioactivity that could not be removed.

The Arkansaswas the closest ship to the blast and was lifted upwards by the rising water column. At 562 feet long (more than three times as long as the water is deep) and weighing 27,000 tonnes, the Arkansas was bow-pinned to the seafloor and toppled backward into the water curtain of the spray column.
