Sadly I have to pic to post, because we didn't have a camera and we had to destroy it. But my friends and I love to make pieces, and we got an idea to make one out of a coconut. So we drilled three holes (with a rock, the caveman way) and put a carrot with a hole through it in one, used one as the carb, and one to suck. And the best part was, the bubbler water was the coconut milk! I reccomend trying this one. It ripped and was quite an exotic taste.
carrots are roots, and when fresh they contain a lot of water, I'm sure it's a lot like smoking out of a potato bowl. Not that I've done that. Hahah. Mmm carrots. Well see I'm trying to say that they should be pretty heat resistant.
