I totally should of invented this: Thumbthing

Whoa, check this out! Simply put the Thumbthing onto your thumb and place into the spine of the book. The two wings will hold the pages open more easily, making reading more comfortable.

It allows you to read with one hand only.

How awesome is this!?! I hate when you have to bend books and have to keep shifting your grip just to hold open a book. This thing solves that problem!

This is also a totally ‘why didn’t I think of that’ invention. This thingy runs for $4.
