i never had that problem w/ rubbing alcohol... bowlsnapper?? that makes no sense because formula 420 contains rubbing alcohol itself... furthermore, liquor is contained in glass bottles... if alcohol made glass bottles brittle, then why doesn't most of the liquor come in plastic or do we hear incidents of the bottles breaking easily? Another point is that most glass is going to break anyways if you drop it... glass is "brittle" to begin with, and rubbing alcohol won't make glass so brittle that it will break if you smoke herb out of it...

Anywho... buy formula 420 if you feel like spending 8-10 bucks instead of 2... it's not my money but i have always used rubbing alcohol and salt, and i've had no problems.
