you can set up a system of a jar in a jar and catch the water vapour
my grandmother worked in a russian factory, she knows this stuff (when I told her about bong cooling, as soon as I started about the tube, she explained everything else :P)
I can make a diagram of what it would look like if you want ... if you had access to a college level chem lab, you could def do it
(and in home if u can get the stuff)
also, my chemistry lab professor says that deionised water is actually a little bit better than steam distilled (no ions which actually cause corrosion)
