if you can't do it, does it work if you think of making two half circles?

i can't do it no matter what i think of!!!! lmao

No problem, a cinch...someone showed me in the second grade and , pratice makes perfect...same concept as pat head and rub tummy, or Versa Vice, that little party game vixen! A great exercise to challenge and develop the brain, not tease it!!

Yes, it's me. The tricky bit is explaining how I do it. Err, it's to do with visualising the pattern of the circles coming together and moving apart rather than focusing on the motion of each circle separately.

Did it the first try. What are you all talking about visualizing, I just did it by , well, doing it O_O

No problem, got it first try, but I'm ambidextrous so I think that helps.

Couldn't do it by trying to do it, but figured out a "trick".

no problem with no confusion at all, for me doing the composite operation is distinctly different for the brain than doing either portion.

what's the trick, blankman!??! i must know!!!

For the ones whos *brain seems at first incapable of pulling it off - try slowly doing a four-part rectangle-like motion instead of the round one, fingers moving in opposite directions. Then gradually turn it into this.
