Soda Bottle Fusing? Anyone ever successfully joined two soda bottles either by heating fusing or by adhesive glue?
I want to take standard 2-liter soda bottle and join a few of them together into a short column. The seam or joint needs to be able to hold together and be air-tight and withstand some pressure. I want to submerge the bottles in the water, and so the joints must be able to withstand the forces against the outside of the bottles. Anyone tried fusing the edges together again; like cutting the bottoms off of two bottles and joining the two cut edges together to form a double length bottle? If so, how did you do it? Any special equipment? Thanks in advance!
