In the Dutch 'version' of this forum they've removed religion and politics as categories altogether after it had gotten out of hand. They also moved all the non-exact sciences to a subdomain. Now they're very strict about posts having a purely scientific background, which is nice on one hand, but a little monotonous as well.

KNO3 is used as a fertiliser. You can buy it at a garden centre or in petshops as an aquarium fertiliser. When I was a kid I used it to make smokebombs

I didn't really enjoy the movie. I found it too long and the plot was a little farfetched in my opinion. I really liked the timeloop idea of humanity saving itself though. What bothered me was that all these miracles in the movie were presented as science. They should've either make the whole thing scientifically sound or admit to the viewer that it's not.
