# 20 Gifs That Teach You Science Concepts In Seconds

###### / Science Gif

There are a number of collections that are like this — collections that aim to demonstrate science concepts in a way that is easily digestible. Each is unique in its own way, and I really encourage you to spend some time Google-ing about and finding all the various lists, as many of them are terribly informative.

Here, full disclosure, we tried to trace down the original source. This means that, if we found something on Reddit, we did a reverse image search to trace down the original creator and original appearance (and listed the credits as such).

Anyways, we hope you enjoy the show.
