Every day seems to bring new questions. And every day, Wonderopolis creates visually stunning (and child-appropriate) videos and tools to answer them. A website and mobile app, Wonderopolis asks questions on everything from the historic (Who invented electricity?) to the universal (What is a black hole?), and finds inventive, fun, and ingenious ways to help you find your way to the answers.

As discovery tools go, we think this one's wonderful. To find out more about Wonderopolis, visit their website: wonderopolis.org
