3rdEyeVision Reviewed by 3rdEyeVision on . I just saw that my bong has a crack in it! I just got this the other day and it's a really nice piece... I didn't notice it after taking it out of the freezer yesterday (didn't leave it in there for too long) but today I saw this huge crack. It still works but it leaks... just a bit :( Jay Rating: 5
