Balloon in a bag - measuring pressure
Happy holidays!

Here is hopefully a contribution to pV=nRT experiments with phyphox.

Put a balloon in a bag together with a phone and pop the balloon with a needle.

Please find my first try attached.

I cannot explain why there are two pressure peeks?

There's 0.04 seconds between each measurement and 0.28 seconds between the peeks (1015.4 and 1015.5 hPa). Pressure in the room is something like 1013.7 hPa.

Best regards.
