you won't be disappointed in these
these are GREAT!! I love them!! So much better than using ice because well, it doesn't melt.  I wouldn't recommend putting one full pack in water.  You need to let them soak for at least 8 hours before use.  Then it says to only putv8 ~ 10 in your bong.  I put a bit more, a little to much one time and I still have a lot...taking up space, in a pan, in my fridge.  I do like them though.  I bought two packs of them so next pack I'll just do little by little.
