If you find a surprise inside of an object, chances are it was by accident – as in, you broke it. Then again, some of us are just curious and want to know what things are made of.

Then there are the moments when you get the bad or weird kind of surprise when you bite into something or cut it open and there’s something in there that shouldn’t be.

From random objects used to add weight to creative ways of “recycling,” you’re about to see some surprising things. And some of them will give you new insight into the way the world works and where some of our random stuff ends up!
