Travis Pastrana's Nitro Circus is running a series on "life size toys." What does that mean? In this video, they consider the humble yo-yo. It was meant to be a kid's toy, but adults got more out of it. I could never get a yo-yo to return when I was a child, but as an adult, I could spin it both down and up. That can be pretty satisfying in a mindless way, but there are those who can make yo-yos into a world class floor show. However, these guys wanted to make a yo-yo big enough for a person to ride on it! They built a yo-yo eight feet in diameter, with harnesses so a person could ride on each side. Then they suspended it from a crane. Will it work? No one on the crew wanted to try it. If you want to skip the exposition and get to the action, go to the four-minute mark in this video. I get the feeling that this is way more fun to watch than to do. -via Born in Space
