I just made this freaking magical bong out of a disposable water bottle, a pen, a mechanical pencil lead case, tinfoil, a pill bottle, and old stick glue! best bong I've ever used and i have quite a few shitty $20 bongs. I put a perc and a diffuser on it and since i didn't have electrical tape, i used old stick glue to air seal it. I used it for the first time today, and i swear, i thought it didn't work at first, cause it felt like inhaling air. I looked down and saw a bongfull of smooth, white smoke. I had a whole half gram rip without ANY throat burning. I tried this shit for the first time testerday and its so purple that two full pipe bowls had me pretty fucked up. This half gram bowl i ripped through like nothing. I LOVE MY NEW BONG!
