Do you remember as a kid when your Mother would say: "Don't tap the glass on the fish tank," then the follow up: "Would YOU like it if some one tapped on your house?" Well this is why you should always listen to Mommy, lol.

TIME reports, the incident happened at the Shanghai Orient Shopping Center, just off East Nanjing Road, on Dec. 18. A massive two-year old shark tank sent thousands of gallons of water, as well as sharks, turtles and other marine animals, gushing into an area crowded with shoppers and retail staff after it spontaneously exploded! Investigators blamed cold weather, combined with the design of the tank, for the explosion.

Fifteen people were injured in the incident, and three sharks were killed.
