So we picked some (non-pickled) peppers today. Well and good.
When my wife bit into one she swears she heard an in rushing of air.
Which led to a discussion. Peppers grow with a hollow space. There’s certainly room for a small vacuum in there. Is there one that is created as they grow? If not is the air pressure inside lower than the ambient pressure and could cause an audible inrush of air?
I told my family that you folks are the people to ask.
The walls of a pepper are soft and flexible. It couldn’t possibly contain a vacuum - if there was one, the pepper would immediately implode. So there can’t be much of a pressure difference between the inside and the outside of the pepper.
I would guess air temperature would be the culprit, like putting a closed plastic bottle in the sun.
In a pepper, no one can hear it scream.
I think someone’s been eating a bit too many peppers, honestly. An audible in-rushing of air, like a “WOOSH” from biting a pepper?
I say impossible.
Maybe someone was sucking on the other end.
It seems possible to be holding a pepper in such a way that tension is trying to increase the inner volume, so when you puncture it your grip causes some suction.
If she just heard the sound, I doubt she could tell if it was an inrush of air or an outflow. Perhaps the pepper was allowed to warm up, thus creating positive pressure inside?
I’d expect the opposite, a decrease in volume/increase in pressure from squeezing it, but I think you’d have to be squeezing it really hard, as in collapsing it, to get an audible whoosh of air; maybe the sound was the knife cutting it.
