Being young would mean having plenty of energy and of course, a decent level of curiosity to explore the world that is around you. The thing is, the older we get, the more sophisticated we would like to think we are, that we tend to miss out on the simple joys of life after that. How about having something that might be fun to kids, but irritating to the adults eventually – the $4.69 Finger Spinner? The Finger Spinner is basically a propeller for your finger, where it will spin as long as you keep yourself moving. I myself would like to give it a go, and somehow, I think it might even end up as surprisingly addictive. A little bit of practice is required before you can pull off an impressive show before your family and friends.
