the rice bong concept works 100% better than water. i went on a boarding school trip to nam like 3 years ago. some dude on his porch in 1 of the towns we visited called me and my friends up to hit his bong. when we hit it and heard no water, we questioned him. he said that instead of agua, he was using dry rice. we were confused at first, but it got us more ripped than we had ever been b4. it was truly an amazing experience. pce:stoned:
