Vsauce is turning into one of my favorite channels on Youtube. I like to describe it as a sort of filter for finding cool things on the internet. If you want to see awesome and hilarious images they have a segment called IMG, for games and other fun things to do on the internet they have another segment called DONG (Do Online Now Guys). But in general you can learn a lot of really awesome things depending on what you're interested in seeing.
They also have a second channel, appropriately called Vsauce2. It basically is has the same feel as Vsauce, but they also cover more things like riddles, and some mind-blowingly cool things under their segment Mind Blow as well as FAK (Facts and Knowledge).
One of the coolest parts to Vsauce is that they link back to just about everything they reference in their videos so if you see something you like you can look into it further.
Here are a couple of my favorite episodes from Vsauce and Vsauce2...
