In the early 1990's I saw an extreme example of static electricity. It was in a university library. I would walk in and walk normally for 5 minutes. Then when I tried to walk out, if I touched the metal pole where people submitted books, I would get a massive static electricity shock. Not just a spark. But a massive blueish white bolt that hurt a lot. Every day that I walked in this happened.
My question is: how would you measure the static electricity force involved? You have two issues  You don't know exactly when the static charge will occur and  then you have to have some way of measuring it. It's not nice and predictable like a Van De Graff Generator.
