Question: how can you make potassium ?

I honestly don’t know. I guess you find something that’s made up of potassium and some other elements, and then take away the other elements. I’m guessing you want to know because it’s so cool when you put potassium in water, and it really is incredibly cool. The problem is, if there’s any water around when you’re making your potassium, it will probably go on fire, and then burn down the building that you’re in, and that really isn’t cool at all.
