invent something essentially useless that brings joy to millions

...one day, but I don’t think it belongs on my list anymore since I’m trying to make it more achievable.

I’m not sure it’s useless – but I hope it brings joy to millions.

Yay for useless crap :)

Something like a yoyo. or a gyroscope. or those sticky spiders you can throw at windows to watch them slowly drop down on its sticky legs. Or those rubber sausage dougnut things filled with water that are hard to grasp. Or clackers. Or space hoppers. Ah, the Golden Age of the useless but joyful things, in the 70s and early 80s. Can it happen again? Its about time it did. yay.
