A boy sprayed a bag of milk out in an elevator in southwestern China.

The video, filmed in the city of Guiyang in Guizhou Province on July 7, shows a boy walking into an elevator with a bag of milk.

After the doors closed, the boy then sprayed the milk over the walls of the lift.

Residents reported it to the property management after they found milk in the elevator.

The property management cleaned it up and checked all the equipment in the elevator for safety reasons. They then found the boy's parents and reported the incident to them.

The boy's parents have apologised and promised that they would educate their child.

7月7日早上，贵阳市乌当区燕山雅筑小区的居民发现一部电梯的轿厢和地板上全是牛奶，空气中还有一股怪味。小区物业调看监控后，竟然是一名熊孩子给电梯洗了一个“牛奶浴”。监控视频显示，当日上午7点17分，一名孩子拿着一袋牛奶走进了电梯，可以看见他手上的牛奶已经打开，牛奶还流了一地。当时电梯里只有孩子一个人，只见他拿着牛奶突然转起圈圈，并将牛奶往电梯轿厢上洒了过去。直到另外一位居民进了电梯，熊孩子才停止了恶作剧。业主将此事告诉了物业，物业及时打扫了电梯里面的牛奶，并安排维保公司把电梯里面的设备全部检查了一遍。如果触碰到按键的话会引起碰电，碰电之后可能会发生火灾之类的消防安全隐患。事后，物业找到了孩子的家长，并把上午的事告诉了对方。孩子的家长表示，对此他们非常抱歉，之后会加大对孩子的教育，杜绝类似事情的发生。（视频由贵阳台提供）
