While assembling part of an electric generator, you realize that two pieces were not properly labeled. One piece is a nonconducting block, and the other is a conducting block, but without labels you don't know which is which. Because you had counted on the parts being properly labeled, you do not have a multimeter, batteries, or other standard electrical tools. All you have is your wool sweater, some nonconducting styrofoam "peanuts" used in packaging, and some string. You are about to go for help when you realize that your knowledge of static electricity should be enough.
