I don’t think there is anyone in the construction industry that has a better marketing department than Priestly Demolition, a demolition specialty contractor based in Ontario, Canada.  Their Youtube channel is filled with high quality demolition videos in the form of timelapse videos and even a 24 minute long, highly detailed video of a bridge demolition so impressive it won awards for best in the world.  Implosion videos are a great source of entertainment in their own right, but the videos that Priestly put out are not only entertaining, but also great for education purposes.
