I made a homemade water bong and it works pritty amazingly. I actually get higher when i smoke outa that than a bowl. I just put a small hole in the plastic bottle, and use a empty big pencap, then i take some scrap metal from a soda can, and made a bowl shape outa it. And that goes on the end of the pencap to store the weed in I dont think its bad for me, because im not really burning any plastic or anything, only the metal from the soda can is getting hot...ill have to post a pic, its pritty cool though.
if you use an apple, it can have potential to rip pretty good. my friend is a cheap bastard and made an orange piece once... but i have to say it ripped like a decent bowl
