As the photo shows, the telescope was constructed using a single empty toilet roll tube. Any household has the raw material necessary for in-home production of the telescope, but Trevor had the innovative idea before others could jump on the boat and sail it away. He also has played with the idea of sticking multiple tubes together, however he found that this technology did not increase the power of the telescope. In fact, the more tubes that were used, the more difficult it became to see out the other end, and, due to substandard sticky-tape, the telescope had a tendency to droop as its size increased.
