Teen Builds Working Submarine

Justin Beckerman must have some incredibly proud parents. This 18-year-old high school student has built himself a personal submarine out of spare parts and a discarded restaurant soda fountain, and it works. In fact, Beckerman has been diving down to 30 feet in his neighborhood lake and can stay submerged for up to two hours. It travels at a speed of around 1 1/2 miles per hour. All this engineering magic for only $2,000 and six months of the student's time (which was naturally cut into by school and homework.)

Naturally we all want to know what else this young inventor has in his garage. It may not surprise you to learn that he has also built boats, planes, and prize-winning robots.
