In this world, we have animal facts, food facts, historical facts, wonderful facts, environmental facts, internet facts, and then... useless facts.
This book is filled with fantastic useless facts that you probably have never heard of and won't make any sense to your life. It's facts that you absolutely never, ever need to know about, but it can make you feel smarter knowing all these random facts that you then can use when you are talking to your friends and family. Maybe someone has never heard that space smells like seared steak? Well, too bad for them, cause you know it and can now call yourself a science expert (kinda)!
After this book, your brain will basically be filled with useless information that takes all your brain's memory when you should have been studying for math or done your history homework. But at least you will be able to impress your history teacher by saying that before 1913, parents could mail their kids to their Grandma's - through the postal service.
