Here I over-inflate three Intex River Rat tubes. One is stock, one is reinforced with a narrow bead of glue on the seams, and the last is reinforced with a glued strip along all of the seams.
From this experiment I learned that cutting off the seam frill prior to reinforcing the toy makes the job easier. Also, Gluing strips to the exterior of the toy was rather difficult and unsightly compared to the interior. The strips worked rather well, and failed as expected, tearing beside the reinforcing strip.
