At the exit it looks like you're playing Sugar, Sugar.
actually these machines slowly run out of water, or you would not need bcln. trust me, i build them.
FrenkeeS: you can do that without BCLN or heating water. I've made something like this not long time ago. 1975161 - here in case you want to check it and take something from it
its not cheating - blcn produce clean water but if you mix water with saltwater it turn all water to slatwater. Even one pixel of salt can turn whole screen of water to saltwater and this is why i made this.
using bcln for water is cheating, it doesnt make salt, it turns water into it.
