pretty fucking sweet man! like someone said earlier for your next bong if you want it clear, boil your water before freezing to get out any impurities.
welp....I love shit like this...so I'ma try to make one.. I'll let you know how it goes or If I even go through with it.. haha
Definitely take pictures if you follow through! I haven't taken mine out of the freezer since the last update, just haven't had much time the past couple days to mess around with it.
