Poland springs for just water...any water will do mixed with some propelh:

We had a name for smartwater...Fart water cuz that shit would either make you fart or give you the runs. I remember drinking a bottle for the first time while walking a downtown sales route and farting like every other step, freaky. One thing it will do is make you regular if you aren't already.

I'm sorry but I'm not drinking anything out of a bottle that could be mistaken for shampoo or hair gelh:
