The "make you go blind thing" is from methanol (what they put into alcohol to denature it), which isnt really going to make you go blind. It will straight up kill you though, if ingested. Rubbing alcohol and isopropyl alcohol/isopropanol are no the same thing BTW.... rubbing alcohol has a oil added to it to prevent it from drying your skin too much. There isnt very much of it, but it is there.
If you are hell bent on doing stuff like this... I'd recommend getting a bottle of everclear.. which is 95% ethanol, 5% water. Go get a carton of magnesium sulfate (from grocery store, etc) spread it out on a baking sheet and dry it in the oven for a couple hours @ 350. After it turns white and powdery, add it to your everclear, seal it up, let sit. you may need to do this more than once.
This will dry your everclear to over 97% the first run if kept closed. You can get it a little dryer, then use that as your solvent. Alcohol is agood solvent for that sort of thing, and food-grade alcohol wont have any other additives. Isopropyl rubbing alc. is usually 30% water, making evaporation a bitch.
maybe you should just buy a sack?
