Sometimes it's hard to conceive how somebody could invent something entirely new, like nothing that had come before it. Of course, not all inventions are completely original and inventors may draw heavily upon ideas that are already around them. However, it's not uncommon for inventors to have a "eureka moment".

What's more, they've compiled that information into a lovely infographic for us all to enjoy. How kind! So, if you've ever wanted to know how tea bags came to be, or why exactly somebody invented the slinky, then you're in the right place! Check it out!
