Many of you might know of Noisebridge, a beloved hackerspace in San Francisco. They had (have?) a juggling workshop every saturday called "Juggling with Judy", taught by Judy Pinelli, founder of the famed Pickle Family Circus (and a huge influence on Cirque Du Soleil).
I had no idea how famous or influential she was. She first taught us how to make our own juggling balls: snip the ends of a balloon, fill with enough rice to feel comfortable in the hand, then wrap that with another balloon to seal the rice in, then snip the ends of the second balloon.
Then she went through the usual sequence: throw a ball, er, balloon, from one hand to the next, then practice with two and so on. By the end of that 2 hour session, we had got the essentials.
The remarkable thing about this workshop was that Judy was at an advanced stage of multiple sclerosis at that point. She was pretty much completely immobile from the neck down, and couldn't even see our hands properly from her wheelchair. She could only see the arc of the ball, but that was sufficient information for her to tell us how we could improve. "Pull your elbow in". "Focus on the left hand, the right will follow".
After the 2 hour workshop, she'd go to Golden Gate park to teach juggling. All for free. I feel extraordinarily privileged. She's been my polestar in life.

I've both been a coach (paintball/martial arts) and been coached (golf) and it really is wild how good your brain can become at seeing the outcome or just a piece of the process and then working backwards to a root cause.
I sometimes make the analogy "in particle physics, you don't actually see the collision. You see the after effects and then figure out what happened by going backwards to what must have occurred."
My favorite version of diagnosing a root cause from an outcome was "Car Talk" on NPR, where somebody would call into the Tappet Brothers's show and imitate the weird sound that the car was making, and then the brothers would diagnose a very specific car problem based on the secondhand impersonation of a weird noise. I have no idea how accurate their diagnoses actually were, but it always seemed like a tremendously impressive trick.

I keep coming back to that. Nobody has ever directly seen direct the force carrying particles, only their effects (indirect evidence). The models make excellent predictions, but I still feel like they're "wrong" in some sense.
This is the only fact we know for certain in physics; we know for sure that our existing models are incorrect. But they sure are great at lots of stuff and correctly predict lots of phenomenon so until someone can come up with a better model they're likely to continue to be used widely!
Great story, thanks for sharing. Just a minor correction: it's Judy Finelli, not Pinelli.
Uh, dayumm. I don't know how I got that wrong.
This is one of the nice things about the juggling community: it's one of the open, sharing communities where people are willing to freely share and teach. It's no cost/low cost entry. The juggling community has been a really important part of my life, so I see it as giving back to teach others.
Noisebridge is awesome. This illustrates beautifully what humans can be capable of.
Noisebridge! I went there as a tourist! I visited SF (I'm from Amsterdam), saw Noisebridge and felt right at home :)
Great story about juggling, thanks.
what means "snip the ends of a balloon"? when I think of balloons they are pretty large spheres for juggling
If a balloon is made of a thin neck and a round body, you're chopping the neck off near the bottom of the neck. You're then left with a round rubber pouch for the contents (rice). Use two balloons in opposite directions so the closed end of the outer layer covers the opening of the inner layer.
Great for juggling balls - nice weight and very grippy.
I think the use of the word "ends" rather than "end" makes it sound like you're making 2 snips on each balloon.
yeah that confused me too
But this means it's a tiny balloon? Almost hand sized already?
Balloons are pretty small before you inflate them, and you're not inflating them, just stuffing them with rice.
I feel stupid, thank you got explaining!
Indeed. Do not blow up the balloon. Just use it as a rubber pouch. If anything is still unclear, describe as detailed as you can the difficulty you're visualizing.
The technique I've used to fill a balloon with rice:
- Take a small plastic drinks bottle.
- Cut the bottom half off to make it like a funnel.
- Remove the lid, and stretch a balloon over the neck.
- Invert the half bottle so the balloon over the bottle-neck is hanging underneath.
- When you tip some rice into the funnel, only a few grains will fall into the uninflated balloon.
- Now put your mouth/cheeks against the open end of the bottle/funnel and blow. This will partially inflate the balloon, and all the rice will fall in. Done!
