#7: Giant Machine vs. Man
This giant piece of metal looks like something out of a Star Wars movie. In case you’re wondering, it’s not a real-life Death Star. Instead, it’s something called a meter tunnel boring machine. The purpose of this machine is anything but boring. If you’re already kind of freaked out by its size, just wait for this next fun fact. This giant circle is just the tip of the machine.

A tunnel boring machine is a super neat machine that carves out underground tunnels. This giant machine is not only extremely tall, but it’s also the length of about 17 city buses. Boring machines allow people to carve out underground tunnels without disturbing the ground above. These machines can create new subway tunnels, and city-dwellers are none the wiser. Imagine something this huge operating right under your feet. New fear, unlocked.
