Voss water bottles, slurpee straw downstem(not diffused yet) 2 - 9 arm percs. Its perfectly air tight, no leaks, i used hot glue for the percs and mounting the base, no sealing necessary, This thing Hits like a fucking champ
If you didn't tell me that was made from plastic bottles, from the photo, i'd have said it was glass (besides the twist cap ridges on the mouthpiece). good work man, that's a pro looking homemade piece
you should probably take out that slurpee straw for the downstem.. im pretty sure youre melting that and inhaling some plastic fumes, i could be wrong though
im gunna have to agree on that its prob a no go on that straw ahaha http://forum.grasscity.com/blogs/morrison/
the slurpee straw is metal, they sold them for a short time at 7-eleven. they fit those cheap bowls with the rubber seals perfectly
