19 Educational Gifs Will Teach You More Than A Textbook Can

The internet is flooded with hilarious animated gifs of jumping cats, running babies and hilarious fails. But there’s a whole different class of gifs out there – gifs that can educate and fascinate. These 20 awesome gifs will do exactly that – show you how the world works.

The cool thing about these animated gif images is that they show just how effective a well-chosen video clip can be, no matter how brief.
