Video: When thing go wrong underground, we're often reminded that the Earth is nothing but a big ball of hot rocks, covered in a delicate skin of smaller, slightly cooler rocks. That became clear on Monday, when an underground water pipe exploded in Kiev, Ukraine. It actually looked kinda hilarious.
The explosion sent water, mud and debris as high as seven storeys, but luckily the only things that got hurt in the incident were some nearby cars, the neighbouring building and, well, the Earth's thin skin. Workers who had installed the pipe still don't know the cause of the explosion, but it's highly possible that Earth was just feeling a little gassy.
