That's one of the interesting things about the class: you learn that even the little things that you use every day had to be designed and then made for mass-production. It's a lot harder than the final product looks.

It's why I like hands-on classes. You learn so much just by doing, sometimes more than what you can learn from just listening in a lecture.

Is this Jack's favorite yo-yo? I dunno. This one is designed to be more of one that comes back easily, so you can do flinging tricks. I'd guess Jack would be more of the type to play with yo-yos that sleep easily.

And now I show you that I learned entirely too much about yo-yos. :)
