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 sloppy that math is.
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.
Also, pee is stored in the balls. It’s a scientific fact.
Ball pits
This is false. They are washed.
Washed in child pee.
They do get washed. Not enough, but they do.
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.
Are ball pits still a thing? I don’t think I’ve seen one in a decade at least.
