They say curiosity is lust of the mind. The more you see, the more you want to know. There are so many ways to view things around you; you can look at them from the side, you can look at them upside-down, and you can even look at them through rose-tinted glasses.

The modern world is full of so many cool things, but how do they actually work? We might not know how these things function, but we can at least know what they look like inside by cutting them in half. Here are 30 photos of objects cut in half to reveal their hidden side.
