How to make Picric acid from Drain cleaner, stump remover, and aspirin
Yes - aspirin. But the aspirin you are I use isn't as good as what your dog gets (I'm not kidding). The Drain cleaner was found at Ace Hardware. Read the label(s). The higher the concentration of sulfuric acid the better (Roto-Root 93%+). If you can't procure some aspirin from your dog - I have another vid (isn't finished) on how to purify your own. This is Marshall - doing "his thing".
