Ballpitts are never washed. Not even once. However, some kids pee in there. This means there is a 100% chance that all balls in ballpits have been peed on, and not washed at some point.

Uh… yeah, they get washed. Not frequently enough for this to be wrong, but still, they do get washed.
There are specialized machines for this that resemble industrial vacuum cleaners but even bigger. Cleaned balls are bagged and get poured back once the floor and walls are sanitized. Do the operators keep track of when this was last done? Yes, and they aren’t proud of it so you won’t see cleaning logs hanging nearby like at most mall toilets.
Don’t forget to wash your balls
EMPLOYEES MUST WASH BALLS BEFORE RETURNING TO WORK.

Speaking as a parent with a horrible experience involving rotavirus:

NEVER, under ANY circumstances should you allow your kid into a ball pit. Just fucking don’t, they are gross and your whole family will puke and shit for days.

Let me guess, youre not vaccinated and nor are your kids?

Rotaviruses cannot be killed by normal sanitizing and nearly all children will have it (and developed resistance) by the age of 5. It almost never affects adults.

Might as well not let your kids do anything at that point, ballpits are not better at spreading rotaviruses than anything else. Ballpits are not clean, but the toys, floors and walls at the daycare aren’t either.

There is a vaccine against rota?
Since the late 90s it seems, and in US since 2006 wiki
Rotavirus vaccine - Wikipedia

We all have every vaccine you can get.

Ballpits encourage contact with eyes, mouth, and nose, then spread it all around over the balls. They are especially difficult to clean. It would be difficult to design a better disease transmission vector if you were trying.

You’re children would be a statistical anomaly if they avoided rotaviruses entirely, ballpits or not.

Rotavirus immunity is partial. You only need to come in contact with a strain too different from whatever your vaccine or childhood exposure was and you’ll catch it again.

I got the vaccine as a child, and yet I caught it in my early 30s for the first time after moving to another country. Have you seen The Exorcist? I didn’t know projectile vomit was a thing for real until then. I also didn’t know about projectile diarrhoea. I wish I was still ignorant of these things

They do get washed. Not enough, but they do.
Also, pee is stored in the balls. It’s a scientific fact.
This is false. They are washed.
Washed in child pee.
Are ball pits still a thing? I don’t think I’ve seen one in a decade at least.
You’d be better off claiming that there’s a 100% chance that at least 1 ball has urine on it assuming that 100% of all ball pits have at least one urine incident.
I prefer Vomit in the Ballpit

Sounds like a Boxcar Children book.

“Eww,” said Violet. “This ballpit smells bad.”

“Maybe somebody barfed,” said Benny. “Anyway, I’m hungry.”

“You’re always hungry, Benny,” said Jessie.

*“Ha-ha, let’s eat!” said Henry.

I cleaned them. Pissing was common enough on a busy weekend I know they need it at least every 48 hours.
Don’t get me started on how mathematically sloppy this statement is.
