I get painful static shocks to my hands where they touch the cart as I'm pushing it around at Costco. As far as I can tell this happens while wearing various kinds of shoes, although I haven't experimented rigorously. Help me devise a method to prevent this that I can realistically implement during impromptu trips to the store.
I don't know much about static electricity, so if I've left out a variable necessary to design a solution, let me know. I will ride this thread like a pony to get to the bottom of this if necessary. It really hurts!
Ok here goes: Wheeling a cart around at Costco (which I need to go to sometimes - I understand that never going there is in itself a solution, but is not the one I'm looking for), I get painful static shocks to my hands, which are resting on the handle of the cart. I assume it has to do with the cart's wheels somehow building static as it rolls across the floor but I know nothing about electricity so tell me if I'm wrong.
My shoes are usually some sort of rubber sole... today's culprit was these.
The cart's handle is metal with a plastic part covering most of it. Even if I keep my fingertips away from the metal, I get shocks from the plastic part.
I don't know what the floors are made of.
I am not an exceptionally staticky person as far as I know, but I must be the only person getting shocked at Costco, because other people aren't throwing their hands up and squeaking pained obscenities every few feet as they walk. Seriously, it really hurts.
The problem was constant some months ago. My solution was to grab a sweatshirt from the car and use it to shield my hands from the surface of the handle; that seemed to work mostly, but was awkward; the shirt would fall, etc. Then the problem seemed to go away for a while, enough that I got in the habit of going again. Today it's back. I had to abandon my cart and left the store. Perhaps dry winter air makes a difference?
Would wetting the soles of my feet (by stepping in a puddle) make a difference? What about wetting the wheels of the cart? Lotioning my hands? Praying to Xenu? All options taken into consideration. Only thing is, it has to be something I can realistically do as I go into the store. I thought about trailing a wire from the cart onto the floor to serve as a grounding antenna, but realistically (1) I'm not going to remember to bring wire and (2) come on.
