In college, I was a member of an engineering team that designed and built a human-powered submarine. It was basically a fiber-glass hull with some bike parts inside for propulsion and controls (it was, of course, much more complicated than that… right…). The majority of the members on the team were ocean engineering students, but we also had some other people heard about us from friends or saw around and stuff. There were aerospace engineers, mechanical engineers, and some math/sciencey people.
The process of designing the sub had us split into different sub-teams, but when it came to construction, everyone helped out. The largest part of the build was the hull. This required a large mold, which we special ordered the last year I was there to work on the sub. In previous years, a plug was made and then the sub built around that. Every year, working on the sub, there were accidents and all kinds of minor “incidents.” But this particular year, we went above and beyond.
The mold that we had made was a female mold. It had an indentation in a large piece of foam in the shape of the hull. We would lay the glass in the mold and just pop it out when it had set. This was better than the male mold we had used previously because the majority of the imperfections in the glass we laid would be on the interior instead of the exterior, resulting in less time needed for sanding.
Every year, there was a tradition of writing our names and the lyrics to Gilligan’s Island in the interior of the sub after it was done, painted, and ready for competition. But this year, a certain member of the team decided that he wanted to be cooler than the rest of us and leave his hand-print in the sub. Now, if you know anything about fiberglass, you’ll know that this is a horrible idea. Instead of just leaving a cool handprint in the sub, he got his hand stuck into the hull. The resin we used didn’t really set that fast, but he had waited until it was mostly set before sticking his hand in it. I guess to leave a better imprint. It backfired though, and stuck to his skin so we weren’t able to pull his hand off.
We ended up cutting a square of glass out of the hull before it was completely set and took him next door to the EMS station. Luckily there were people there and they had some kind of solvent to get most of the goop off the guy’s hand. That piece of the hull was ruined though. Which meant that this hull we had spent weeks getting ready now had a hand-sized hole in it. However, being the clever kids that we were, we worked that into our sub as a “feature.” We made a new square that was separate from the rest of the hull and hinged it in place on the bottom side of the sub. This was our new water release hatch. It actually came in really handy at the competition, so it all worked out.The Omen full movie download About Last Night… movie
