Okay so I get pretty crazy with the homemades so I thought I would share my ideas or ideas that I got from others, but decided to make. 1. This is a smart water bottle with a choke this can be replaced if it breaks. Or if I improve it I can use it. Or if I want interchangeable bong parts.. lol build a bong 2. This is a two caps stuck together that has a hole in the middle of it. 3. This is the bottom part that I dont want to make another part of. The top is the main interchangeable part. This is just one of those new globe coca cola bottles witha onie in it and a cap over it to make it look good. ________________________________________________ This is my next design I finished making the perc. I am making big holes in all the pieces to create less drag. I was high when I tried to make this the first time, and didn't realize that the hot glue gun would melt the smart water bottles... Off to the store I guess..
