How do you solve a problem like demolishing 19 blocks of flats?

With five tonnes of explosives that's how!

The demolition happened in Wuhan, China and was to make way for a new 700m tall skyscraper and business park.

Officials said “The demolition effect was quite ideal." And also that the massive explosion "didn't affect the light rail and public facilities around the blasted buildings."

Which is a good job as right next to the demolition site are a number of busy roads and also a railway line!
