I found some howto's on DIY juice, but was wondering.  Where can one get PG?  I know it is the primary ingredient in RV antifreeze, and no-one in their right mind would use RV anti-freeze for anything other than what the label says! but there must be a pure, edible form available somewhere.  Also, has anyone made a mix calculator for a PC? (Linux preferred but windows will do)  I dont have an IPhone (Shocking, I know)  Even just an equation will suffice.  If PG is not available, then how would one thin the VG down a bit?  Use water?  Is there any need to thin it if one is careful to practice safe vaping with VG only?
Thanks folks!
