If you're in the mood to expand your mind, Brain Pump is a simple site that plays random educational videos one after the other, on a myriad of topics. You'll start off by learning about procrastination, then move into something like astronomy, or history, or maths, randomised per visitor.
The site is pretty simple, but the idea is that you can sit back and learn something interesting and new without thinking about what category or subject you may want to dive into. Some of the videos may be ones you've seen before — we caught the site playing back some videos that have been featured here before — but you can always click the forward arrow to skip one you've seen before or don't care to watch.
If you like what you see, you can share the video on your social networks, or you can sign up for Brain Pump's mailing list, where you'll get five educational videos delivered to your inbox every week. Hit the link below to check it out.
