Hi everyone! My name is Bonnie. I’m a hat juggler living in Hawai’i and the lead organizer for the Hawai’i Island Jugglefest.
We just had our festival last weekend and it was super fun! My goal next year is to win the club balance competition (I got 3rd place again). I also want to get better at passing :) It’s nice to meet you!
Hi Bonnie, welcome aboard! I’ve been known to twiddle a hat or three myself. Good luck with the balancing and the passing, but most of all with the fun. :-)
Here are all the links posted during February 2025:

Hi all,
My name is Anton and I am currently working on getting my 5 clubs back to being solid! I might go to the EJC this year as its quite close being in Holland...
Hi Anton,
Welcome to the Edge. A Dutch pedant might argue that EJC is in Gelderland not Holland, but both provinces are in the Netherlands. Hopefully see you at EJC.
Welcome Anton. Hope to see you there: should probably make an effort when it’s in my home country.
And as for Dutch pedants: yes, they’re easy to find. But it’s also easy to spot people supporting Dutch national sports teams waving banners with ‘hup Holland hup!’ and the like emblazoned across them, so it can’t be the worst mistake to make.
Juggling Equations
I've been looking at juggling through a more mathematical lens than I usually do, and I've found some interesting relationships. The variables I'm going to use are as follows:
S- siteswap value
P- Period
X- start location in the pattern (ex. x in any period 3 pattern is 123)
D- End location in the pattern (ex. D in 531 is 321)
L- the number of times something 'loops' through the pattern (ex. the 4s in 441 loop once, the 1 doesn't loop). The mathish way to say this would be S mod P, but it makes more sense here to just say L. (Note: L can also be based on a value that isn't S)
W- the number of times a throw crosses the right 'edge' of a pattern, including after it 'loops'. This number can be similar to L but is NOT the same.
O- the number of objects in a pattern.
I- (If the font doesn't distinguish, this is an i, loop is an l) The total 'distance' a throw travels in the pattern. (ex. in 441, I is 111.)
That's a pretty good heap of variables. Using these and some logic, we can define some relationships. I'm going to use # as a summation sign, meaning the sum of all of that value in a given pattern. For example, #S of 531 is 9. I hope that doesn't mess with the hashtag system... On paper, I use a capital sigma like in math.
First of all, the one everyone knows:
O= (#S)/P
Which gives you the number of objects in a pattern.
We can also say that
I= S-LP
because -LP essentially takes the loops out of a siteswap value, leaving only the smallest possible value, which is what I is.
A helpful way to check validity is to see that there are as many of each D value as there are of each X value. Translation: each throw has exactly one start and one end. Because of this rule, we know that
#D = #X
But the most important relationship I've found is that
WP+D = S+X
which I got to via experimentation and logic. I don't really remember all of it, but trust me. (I think if you try to find a way to get from S to D mathematically, this is probably what you'll come to.)
Anyway, now that we have these relationships, we can substitute some of them together. For instance:
WP+D=S+X --> WP-S = X-D
--> #W P - #S = #x - #D
--> #W P - #S = 0 (not object number, value zero)
--> #W P = #S
P behaves a little bit strangely, but best I can tell, summing it does nothing because it's one value throughout the whole pattern. Questionable logic, I'm aware.
But we can then take that equation and see that
#W P = #S --> #W = (#S)/P
and therefore:
#W = O (Object number, not value zero)
and that's the basics. In summary,
O=(#S)/P
#D=#X
WP+D=S+X
#W=O
The following gets crazy and probably hard to follow:
And now, for a stranger and more theoretical equation. It can be used to convert siteswap values into state values, and it is pretty janky.
Here is some notation I will use and other details:
- Each value in a pattern can be treated as a set of values. For 441, S= [441], X=[123], W=[111], L=[110], and so on.
- A subscripted number can be used to indicate what item of a set is to be used. for example S3 of 441 is 1. When a variable is subscripted, each value of that variable is used to create a set with one more 'dimension'. Single value--> list --> matrix --> so on.
- There's a mystical magical set that I usually call psi, but on the computer I will use %. %=[123456...]
- A range of values can be indicated in a subscript like so, S1~4, meaning that values 1 through 4 of the set are to be used.
- A different base value for L can be indicated using //, example L/X+3/. (For any period 3 siteswap that would be [120] because X+3=[456])
- St is a state value. State is notated by giving the position of each object. For example xxox would be 124.
With that out of the way:
S+X-P(L/S+X/ - %1~L/S+X/)= St
Which took entirely too much time to find. But we can also rewrite that as
S+X-PL/S+X/+P%1~L=St
and
I+X-P%1-L/I+x/=St
I use 'music rules' for this, meaning you only define L the first time you use it, unless it changes. Also good to note that for some reason, the P% in one is positive and in the other is negative. I think that has to do with L being based in different numbers, but I honestly don't know. I'm a bit too tired to find out at the moment.
Anyways, if you read through that, really really well done. I struggle to understand some of this sometimes, and it's far far cleaner on paper. These are the most refined siteswap to state conversions I have found so far (there are others but I don't like them as much). If you find an error in the math part of it, that would not surprise me, but they work as far as I can tell. Further testing required I suppose.
Anyways. There's that.
("cleaned" versions of the equations:)
S + X - P (L/S+X/ - %1~L) = St
S + X - P L/S+X/ + P %1~L =St
I + X - P %1-L/I+x/=St

Revision:
I have checked the SS-St equations while less tired, and they are all wrong (not completely, but definitely wrong.) The revised equation is as follows:
S + X - P %1~LS+X = St
Also note that when creating %1~LS+X, it will be a weird matrix; not all rows will be the same length. That's because the matrix concept is just a neat way to do the whole siteswap at once.
An example of using it:
S=414
[414] + [123] - 3 %1~LS+X
[537] - 3 %1~L[537]
==> L[537] = [112]
[537] - 3 %1~[112]
splits into
5 - 3[1]
3 - 3[1]
7 - 3[12]
5 - 3
3 - 3
7 - [36]
[2041]
which is equal to [124], which is the state of 414
Update on British Juggling Convention 2025:
There will be a Facebook roundtable meeting - a chance for jugglers to ask the organisers questions on Wednesday (19th Feb) evening see www.facebook.com/britishjugglingconvention/posts/pfbid0tqCGyTRJEuYfzE2DSwULnXZRSP5BPtXRACs7MexH21J27UrjzHRRSCNvNZdH7mUDl
you can submit questions prior to the Wednesday meeting at https://forms.gle/K8iKGaKU36ukWzrt8
The organising team have also posted the following message on Facebook today:Announcement - A letter to the community.
Dear British Juggling Community,
It's with a heavy heart that I must share that we are likely going to have to cancel the British Juggling Convention (BJC) 2025. Since our initial announcement, a vocal minority has been extremely active online, and I feel it's important to address the community directly. We'll also be hosting an online Q&A tomorrow where you can speak with me and the team. I truly wish there was a path forward, but this is a community event, and it relies on community support, which is sadly lacking at this time.
It's been particularly disappointing to see this negativity given the current climate for juggling and circus events. With the BJC facing cancellation and other events like Play festival no longer running, it seems there's a lack of understanding for the immense effort and resources required to make events like this happen. We had hoped for a more collaborative spirit in facing these challenges and ensuring the future of juggling conventions.
For context, I'm Luke Hallgarten, Artistic Director of Revel Puck Circus. My connection to this community is deeply personal. I've been a juggler since I was nine, volunteered at Oddballs from ten, and even worked there at thirteen. Juggling led me to circus school in London and then Le Lido in Toulouse. Now, I lead The Revel Puck Circus, a not-for-profit circus with a mission to redefine the art form.
The BJC 2025 story began with a phone call late last October. We learned that effectively the event wouldn't happen unless we took it on. My team and I immediately considered the challenges: the financial risks, the significant workload, and the incredibly tight timeline. A concern we held, echoed by many in the juggling community, was the need to ensure a safe and welcoming environment for everyone.
We'd heard feedback about past conventions regarding experiences like "cuddle puddles," nudity in unsupervised spaces, and a demographic imbalance. We also heard from a youth circus facilitator who took their youth group once, and didn’t feel comfortable taking them again. It was clear we needed to proactively address these issues; they didn’t need to define the community or the convention, but they needed to be addressed seriously.
The question became: could we take on this substantial financial risk, the massive workload, and organise an event in such a short timeframe, especially given its past reputation? My answer was yes, but things had to change.
Why yes? Because juggling conventions matter. They bring together people from all walks of life who share this wonderfully unique passion. My own convention experience at age 13 was transformative. It fostered confidence and ultimately inspired my career in the arts. Juggling conventions matter, personally and deeply.
So, we got to work. We rearranged our tour schedule, secured local authority support, carefully considered the finances, and, most importantly, we focused on how to do things differently and better.
I'm incredibly proud of what we'd put together. Our vision: a convention that truly celebrates juggling, that's inclusive and safe for everyone, fun, and inspiring. It was also essential to me that the event remained true to the original proposal I submitted: Click here to view.
Inevitably, some things were going to be different. This is the first time a professional events organisation has run the BJC. We operate under rules and regulations with serious consequences for non-compliance. We’re not a volunteer organisation. Our overheads are significant, and our cash flow is tight, particularly at the start of the season. With current ticket prices, we need to reach 80% capacity just to break even—that’s double the standard risk for an events company.
We’d created a fantastic program: two circus tents, a bar and chill-out space, camping with showers and charging points, campervan spaces, a town parade, a juggling hall open 12 hours a day, plus squash courts for workshops and other activities. We knew we had to create warm, dry, and enjoyable spaces. A 24-hour juggling hall, however, wasn't feasible given the necessary capacity limits for a safe and comfortable environment. From 9pm onwards, there would be a variety of social and juggling activities on the circus site.
The most prominent concerns seem to revolve around ticket prices and the limited juggling hall hours. To be transparent: VAT accounts for 20% of every ticket. We also must pay everyone who works on this event. This isn’t a volunteer-led endeavour.
It's been incredibly disheartening to see the community's reaction to a not-for-profit circus trying to do something positive. Especially considering that no one else was able to run a BJC this year, and other events like Play festival have been discontinued. The financial risk and responsibility of putting on an event like the BJC are simply not what they once were. Furthermore, the two female producers leading this project have had their phone numbers circulated, and they’ve been bombarded with calls, messages, and Facebook requests day and night, seven days a week. This is simply wrong.
I’m deeply saddened by this response. To the new generation of jugglers, I want you to know: these voices complaining about "how it used to be" do not represent the entire circus community. We envisioned an event for everyone.
We are currently exploring three options:
- Continue with the event as is: This means proceeding with a community that doesn't seem to fully support it and risking a significant financial loss for Revel Puck.
- Reduce the ambition of the event: If we eliminate camping, we could offer a day ticket for around £40. This would significantly change the event's feel and scope.
- Cancel the event completely: This would be a deeply disappointing outcome for us but is the most likely.
We want to be transparent and give the community some agency in this decision. We will continue to explore how we can support future community-run events where everyone feels welcome and safe. In the meantime, I want to say a massive thank you to Start Thurrock, Thurrock Council, the Pucks producing team and all the support we have received from positive members of the juggling community.
See those of you tomorrow for the Q&A if you’re able to join.
Sincerely,
Luke Hallgarten
Artistic Director of The Revel Puck Circus (and 2008 British Young Juggler Of The Year silver medalist 🥈)

And the latest update in short is that there’s now a questionnaire to gauge interest in a £40 one dayer. Geography makes my decision easier but it still seems expensive to me.

After the 5 days of polling the results are now in; sadly it looks like there is not going to be a BJC this year, not even a one-day BJD.It is with a heavy heart that we will not be going ahead with a British Juggling Day. 46 people said they would definitely buy a ticket, and with the 200 number being the break even point, we are unfortunately going to have to cancel all together.
We are down around £3,000 of non recoverable costs, and have set up a support page for anyone who would be able to donate towards covering this: https://gofund.me/5620dfd0
We would like to thank everyone for there messages of support and offers of help, unfortunately it comes down to the numbers at the end of the day. We sincerely hope that BJC/D might be able to happen at another point in the year, and wish any future organisers the very best.
With love,
The Revel Pucks x

Poll Results:
I would like BJD to happen
97 = number of Responses
47.4% I will buy a ticket as soon as they go on sale
26.8% I will think about buying a ticket but can't guarantee my attendance
18.6% I will not be able to attend but like the idea in principle
7.2% I will not attend and don't think it's a good idea

I am really upset to find that BJC is cancelled. I can't claim to be an active community member, but I do love BJC. Been to every one since 1993, and I even have the bones T-shirt from 2019 when that didn't happen.
I was away for a few days last week (though checking email) and half an hour ago now I thought... must just check about BJC. Now I discover Miark's message of three days ago that it is (again) cancelled.
But I did register for email and received an update on 20 Jan telling me that tickets would "soon" be on sale. I would have been happy to buy an early bird ticket with an extra donation (which I normally do for EJC). Looking back here, it seems that tickets only finally went on sale on 13th February. I did not receive an email (yes, checked spam folder): I would have bought a ticket as soon as I got that email.
While I appreciate that taking BJC on was a big thing for Revel Puck to do, it appears that they have only communicated via Facebook. I do not, have not and will never use Facebook: I suggest that several people like me don't even know that tickets ever went on sale, let alone that that it's now cancelled.
I don't want to blame people who have made a genuine effort, but I am asking what went wrong. A reasonable number of folk turned up to Ramsgate in 22/23 and Lytham last year. I am aware that a group of people were planning a foundation to provide year-to-year support for BJC (I went to the meeting at Ramsgate in 2022). There is a web site https://britishjugglingconvention.co.uk/ (still advertising that BJC will be in Essex).
What do we have to do to make sure that BJC continues?
There has not been a lot of information on facebook (though much more than instagram or twitter) despite the BJC 2025 team employing the services of a professional community liaison person I don't know which community they were liasing with or where/how.
On facebook there was the message in November saying Revel Puck would be organising BJC 2025, a message on 20 Jan with the BJC 2025 dates, 29 Jan advertising ByJotY, 4 Feb asking for workshop organisers, 12 Feb tickets on sale announcement, 14, 18 and 19 Feb announcement of online Q&A session to answer the many concerns people were having (eg no indoor space after 9pm, only 2sqm per tent, increased costs of running BJC as professional not volunteer venture, etc), 19 Feb online Q&A, 20 Feb announcement of BJD one day convention and poll to see who would come, 25 Feb announcement of BJD poll results and decision that BJC would not happen.
Luke and his Revel Puck team took on an incredible challenge of trying to organise a BJC in only 6 months when the previous BJC 2025 team had to give up last October, it is a shame it did not come to anything. I believe there is a BJC foundation being set up, but they are still completing the paperwork to become a foundation.

OK, Miark, thanks for the info and again thanks for passing on the info.
I'll repeat that taking BJC on is an huge thing for any team to do (and mos definitely not my skills, technically or psychologically) and so I admire anyone who does. This isn't a gripe at Revel Puck. I've given them some money; thanks to Luke and his team for what they have done.
But I still want to know how we can avoid this in future.
If anyone here has news of the BJC foundation - and who can update their web site - I'd appreciate a post here.
This Saturday is Chocfest 28, the first juggling convention in the UK juggling 2025 calendar, and we would love to invite you all. This year we are at a new venue at the University of York, which means we can have lots of aerial and acro workshops as well as a full day packed with all the usual activities; juggling, workshops, games, tea/coffee, etc and the Chocfest Chocolate Cake Contest (enter a cake a get £5 discount on admission).
a few more details on website www.chocfest.com
See our programme of workshops https://circustimetable.com/chocfest2025#timetable (thanks to Callie)
Hopefully see you all there 🙂
#chocfest2025
https://www.chocfest.net maybe?
See you tomorrow!
York Jugglers - - Vorredner #
Yes, thank you.
I could try and pretend it was a delibberate mistake to see if anyone read my post, but that wouldn't be very believable. ;)
See you tomorrow

Hello :-)
I am Tibor from Karlsruhe in the south of germany, juggeling for a long time but only as a hobby (never had the endurance... ).
So i am still working on five balls, but prefer to train on easier / achivable 3 /4 ball things :-)
Currently i am a small part of a small team organizing the next Karlsruher Juggle Convention in Karlsruhe from the 11. to the 14. September in 2025
Best regards to everyone and keep on juggling :-)
Tibor
Hello Tibor,
