A shark tank broke last week in a mall in China, sending 33 tons of water, three lemon sharks and other animals flooding customers in the shopping center.

The tank's 5.9-inch acrylic glass cracked and then burst inside the Shanghai Orient Shopping Center on Dec. 19. Fifteen shoppers were injured and three sharks died, according to Gizmodo. Most of those injured suffered "deep cuts and bruises" because of flying glass, a police spokesman said. Fish and turtles were also released from the tank.

The animals reportedly did not cause the injuries, but rather it was the aquarium's broken glass that injured the 15 people, Examiner reported.

The aquarium was installed two years ago, and video of the tank busting and flooding the mall was caught by CCTV cameras. Deadspin quoted a spokesman for the mall who said "they are not going to build an aquarium again in the future." No word yet on how or why the tank cracked.

The same month that this devastation occurring in China, the country unveiled the world's longest high-speed rail line, extending 1,428 miles. It's first trip took place on Wednesday, Dec. 26, with a 9 a.m. departure going from Beijing to Guangzhou. A second train left Guangzhou for Beijing at around 10 a.m., marking the first pair of trains on the new rail line.

Trains running on the line will run at 186 miles per hour and will cut the travel time required to go from the country's capital of Beijing in the north to Guangzhou, which is in southern China, by more than half. Travel time between the two cities by train was more than 20 hours but now will be around eight hours.

A north-south line connecting Beijing and Shanghai opened in June 2011.
