This was amazing to watch. Highly recommended.
I do start to wonder if any of such materials are stored like this in one of our ports, such as Rotterdam, The Netherlands.
I can't imagine such a mess to exist there.
But The Netherlands remembers the Firework explosion in Enschede, from 2000. https://en.wikipedia.org/wiki/Enschede_fireworks_disaster
It's not nearly at the scale of Beirut, but it killed 23 people.
