Guess the weight, win a thing!
Today marks the four-year anniversary of Nicola Early joining the Raspberry Pi team. Nicola works as Administrator at Pi Towers and is responsible for so many things that I dare not try to list them all. But among all her tasks, the most important one is the care and maintenance of the office rubber band ball.
The rubber band ball chronicles
Every working day for the last four years, whenever the postman delivers the packs of letters, Nicola has had at least one new rubber band to collect. And so over time, the ball has grown and grown and grown.
Nicola is very protective of the ball, so if you come to her desk in search for a rubber band, you’ll have to withstand her glare as she reluctantly removes one from her expanding collection.
If we are to consider that, in the UK, there are about 261 working days in a year, and Nicola has been working at Pi Towers for four years, it’s fair to estimate the ball consists of at least 1044 bands.
So our question for you is this:
How much does the ball weigh?
Submit your guess in the comments below*, or in the tweet, Facebook post, or Instagram post for this blog, and the closest guess will win a Raspberry Pi T-shirt and, if we can manage it without her noticing, a band from the very ball in question.
To take part, you need to submit your guess in grams by midnight next Monday 17 September. Multiple guesses on the same platform from the same account will be ignored — so behave.
*Members of the Raspberry Pi team may not take part, as there are scales on Nicola’s desk, and I don’t trust any of you.
Can my guess be the average (mean) of all the other guesses?
603 grams (is it supposed to be in grams?)
587 grams ?
317gr … ?
Or maybe 600g
Is this a european or south african banana ;)
american, south american.
Don’t think on the joke while typing. Don’t think…
I discovered that the wikipedia page is fascinating, and Nicola is far from breaking the world record ;)
Mr chris stagg
grams or pounds?
Knowing that an average postal elastic band weighs in at 0.75g my guess is too bloody much lol
About 800g to account for there being 2 some days

Teniendo en cuenta que yo tengo en casa una de 200gm y es la mitad de mi mano,la bola que aparece en la mano de la foto…calculo que esta bola,siempre que esta sea la real que aparece en las fotos….es de unos 487gm mas o menos.
I think it is about 1600 grams…
-Nice idea and greetings from Germany :D
Nicola doesn’t have holidays? 720 gram!
542 grams, maybe :-)
Does it have a titanium ball at the centre? ;)
I’m going to go for 253g.

Nevermind. I suck at math.
Probably 31.28 oz
You go to a stationery “store” not shop yet your name’s ukscone. I bet you speak with an American accent when you come back from a holiday in the states too. [edited by ukscone to remove inappropriate word].
as i’ve been living in the States for about 28 years it’s a blooming long vacation :P
It is obviously 628,318530718 grams!
I would guestimate about 255 grams (g) or .562179 pounds (lbs).
If it isn’t 314.15926535898 grams, then I feel that a disiplinary hearing should be held, and those responsible should face summary execution (or whatever the current penalty is for creating inadmissable ball dimensions).
666g – is there a pentagram emoji?
I think it is 970 grams.
If this was a repost of my other comment sorry, it wasn’t showing up on the site.
My guess is 294 grams
769 grams or 0.03 Grammas.
I would say 800g.
2200 grams I think
i’d say roughly 521g =)
729g based up my own rubber-band ball and banana.
My guess is 698 grams.
If it’s too much, add some rubber bands, please.
I’d say 2580 grams
No idea how many pounds that is…
In for a penny,
My guess: 268g
My guess: 473g
288grams ball envy!
(Based on scaling up the mass of the similar ball of PO rubber bands on my desk, and assuming that’s a typical Cavendish banana…!)
Are we guessing for the weight before or after the winner’s band is removed?
I think it is 270g!
687g. So there!

My guess 1140g.
I assume a natural rubber (d) density of 0.93 kg/dm^3, a band spherical packing of 75% (p) and Alex? hand as medium sized, giving a ball radius (r) of 5cm.
This leads to an actual rubber volume (V) of 4/3 pi r^3 * p and a weight of V*d.
Given my precise error-free calculation my guess is 392,7g for today, as there is uncertainty on the steadiness of pi: https://physics.illinois.edu/news/article/10665

thus making it a banana pie
319 gr !
The rubber band ball should weigh in around 680.39 grams or roughly 1.5 pounds.
Who won? :)
