The colder the water the easier it is on your throat. If you used hot water it would burn your throat really painfully. If you use ice (with water), then you can take the biggest toke ever.

Put the bong in the freezer, take it out when its cold, add the water and a few ice cubes and toke away!
DataMatrix Reviewed by DataMatrix on . Hot or cold water in a bong? Which one? Does it make a difference whether you use hot or cold water while tokin ya bong? I don't have one so I can't find out myself, so what's up? Does it make a difference in the intensity of hot (boiling) or cold (icy) water as opposed to normal temperatures? Rating: 5
