I think I recorded this last summer.
Jumping on the trampoline, we discovered that if you have a static charge and slowly approach another’s nose with your finger (provided you’re in a dry climate like Utah?), that you’ll hear invisible static bursts jumping rapidly from you to the other person while your finger is still relatively far away – the bursts rapidly increasing until you get close enough to discharge all the static electricity.
The crummy little 16 Mhz recorder I was using doesn’t capture the whole range of the audio, but if you listen closely in this you can hear these increasing static micro-bursts at the lower sound wavelengths it could capture.

Thousands of volts! Glad you both lived to laugh about it!
