One night I was so high and though about it... but I thought that it would catch on fire because of the alcohol in the mouth wash. So I grabbed some ice and put it in the mouth wash and let it sit. Put the ice in the bong and smoked... let me tell you... NOT A GOOD IDEA. It taste wierd... and ewww... just eeh.. no... I wouldn't try it because my experience wasn't all that great.

Its pretty gross and a bad idea.

Good luck with that.
