Ever stuck a balloon to a wall or make ya hair stand on edge ? Balloons are made with latex and are great for creating a static electric charge. Nix the latex gloves.http://www.fi.edu/tfi/activity/energy/ener-2.html
And I don't use a wrist strap, gloves or anything else. I work at a wood table with hand on case, psu plugged in but turned off to provide earth ground. Make sure to have nothing on ya feet that walking on floor will create static charge.
