Re: Dry Ice
I've said it before, I'll say it again:
The hookah base is made to hold water, and nothing else. In a half a millenia of hookah smoking history, if there was some awesome, groundbreaking chemical that could be added to the base, it would be what we are using now. Water remains the constant because it works better than anything else.
Enjoy it for what it is.
