OK, I'm aware of the behaviour of static charge (like every fifth grade science student).
I doubt very seriously that a fifth grader understands the complexity of static electricity as many scientists are bewildered by the phenomenon.
Where does the charge build up when cleaning a MAF sensor with spray?
I don't want to get into the theory here, you can do a web search for that. Here is a hint:
PROJECT 2 - Bending water
What you need:
a hard rubber or plastic comb, or a balloon
a sink and water faucet.
What to do:
Turn on the faucet so that the water runs out in a small, steady stream, about 1/8 inch thick.
Charge the comb by running it through long, dry hair several times or rub it vigorously on a sweater.
Slowly bring the comb near the water and watch the water "bend."
This project can also be done using a balloon instead of the comb.
What happened: The neutral water was attracted to the charged comb, and moved towards it.
Liquid movement thru a tube, and sometimes the atmosphere causes a separation of the charged particles, just like walking across a carpet, especially if the liquid is moving at high speed.
And why is it any more dangerous than the guzillion other static charge producing moving parts around your vehicle?
Because it is applied directly to the sensor. A static charge does nothing as long as it is static (not moving). Only when there is particle separation does a condition exist for particle movement. shady
