These are the kind of things I solve when I’m bored.
I set a problem to myself to figure out how just using one hand and nothing else, to make all 5 fingernails to touch something on that hand.
If you’re bored like me. This is a fun puzzle.
I solved it. See if you can.
To make the problem more difficult, make sure that each fingernail is touching another fingernail - I solved this as well.
These are clipped fingernails. Not that dude who has 5 foot fingernails.
