I love Ghetto fix up/make shift bowls and bongs. They're fun to make and if you do it right cheap to use. I only own a small metal bowl, I'd upgrade to glass but I don't have the cash. So Here's a picture of the Pringles can bong I made and named 'Bongzilla' And a pic of my bowl 'Illaddin'
Sometimes u can have the best of both worlds...glass makes homemades so easy: [ame=http://www.youtube.com/watch?v=rnsT9zhxiSc]Reverse Gravity / Waterfall Bong using ehle dowstem and roor bowl - YouTube[/ame]
