I remember when I chewed. We'd cut the top off a 2 liter bottle and use that. We called it a crappie cause it smelt like dead fish. Spilled a full one a few times and boy does that reek. Almost blew chow cleanin it up.
Anything you can get your hands on... don't do it anymore though, bad for the teeth.... once I just wheeled a cart out of the way and spit on the floor- then moved it back when I was done....
