Engineers fail to demolish a building with 300kg dynamite

Old building was needed to be demolished. 300kg dynamite was used, but it didn't even collapse. They tried one more time and that also failed.

Expert at 2:23 says problem is the structure of the building; as the building was so strong due to the fact that it was built fully with iron and cement, without bricks.

The demolition was postponed to another day.
