The Panama Canal is a wonder, a massive project that took well over ten years to complete. An estimated 23,500 people died in the process. It is a series of locks where water fills and drains allowing huge ships to traverse what was once dry land. It reduces the shipping route from New York to San Francisco by 8000 miles. It's still a long journey though, but now you can do it in the minimal time you should spend brushing your teeth.
