I read in a book (my mind is open) that Ronald Graham - a famous
mathematitian - can solve 3 rubiks cubes simultaneousely while juggling
them! I can solve a rubiks cube and I can juggle, but I wouldn't know
where to start with solving them while juggling them. For a start, it's
very difficult to solve a rubiks cube using one hand and how would you see
what move you have to make, make the cube fall into your hand in the right
position and make the move before you have to throw it again? Perhaps he
juggled 2 in one hand while solving one in his other hand and then swapped
them over when he finished.

Does anyone know if anyone has actually done this?

I once saw a video of him on my local news and he was indeed juggling a
cascade....but i don't know...it still seems shady to me

There is a magic trick involving a rubiks cube where it solves itself
magically when you throw it in the air. I think Daryl in the USA sells it.
I expect this has something to do with how he did it. Or maybe it was real?

As an employee of Bell Labs, Prof Graham's former employer, I decided to
email him directly. He was kind enough to respond and here is what he said:

"I think this story got embellished with time (as many stories do). In
fact, I did work on
restoring one Rubik's cube while juggling three of them, but the only
way I could make any
(slow) progress was that two of the cubes were juggled in one hand,
while the other hand
(and most of my attention) was focussed on the remaining cube. After
deciding the next move,
it became a matter of twisting the appropriate face with one hand, which
takes a little practice.
Definitely, this is not the best way to restore a cube!"

Wow, you can't get a much better reply than that!

What if you juggled 5520 and did a twist of the cube on the 20 part. Would
that work?

Hey, everything's already been done folks!

IIRC...
About 20 years ago Edward Jackman was regularly performing a routine
where he solved a Rubik's cube while juggling it, the exact details of
which escape my memory now. It might have been a one cube, two ball
juggle, or three cubes solving just one, or the cube was preset to a
known state, or whatever, but it was something.

my memory says it was two balls and one cube which was about four moves
from solved (enough to look pretty mixed up to the average eye, but not
actually all that mixed up), and that he'd do a two-high, quicktwist
move. at the end of each street performance he'd set the cube back
up, ready for the next show.

I thought of that yesterday when I read this thread - an easy way to make
it look mixed up in a few moves is to twist the right side away from you
and the left toward you, turn the cube 90 degrees to the right with the
same side on top and do that move again, turn 90 degrees, etc. But it
would be hard to get the cube to land in the correct orientation to fix
it. In my mess up method, the center dot should stay on top when you mess
it up, but even still you need another dot (or two) to verify that you
have it oriented properly. So, it sounds pretty tricky even with a
gimmicked mess up because you'd have to be sure of the orientation 4
times. I don't have a cube in front of me here but I assume that it would
be pretty hard to do. But I'm sure most of it is how you perform it, play
it up for comedy, and make it look harder than it is.

The problem (*one* of the problems) is that you would likely have to keep
the cube oriented a particular way while you throw as you won't have enough
time to search the cube, looking for the correct move.

I don't recall how many turns it typically takes to solve a cube (it
depends on method, obviously) but my solution time runs around a minute
and I imagine it would take me 10 minutes or more to solve one while
juggling, even if I got around the above problem.
