Sorry, couldn’t resist the teaser tag but here’s a video of a massive propane plant explosion on the weekend in Toronto. When one of the big tanks bleves you can see the shockwave from the explosion.
Fortunately there were no deaths as a result but over 12,000 people were evacuated and Canada’s busiest 16-lane highway was shut down for 14 hours until firefighters got it all under control.
