he tool a student says his science teacher used to burn a cross on his arm comes with a warning: Never touch or come in contact with the high voltage output of this device.
When the boy's parents complained, administrators at Mount Vernon Middle School told John Freshwater, the school's eighth-grade science teacher, to lock up or remove the BD-10A High Frequency Generator from the classroom. About the same size and shape as a power screwdriver, its tip puts out up to 50,000 volts of electricity.
Science teachers use the generator to ionize gases in a test tube so that students can identify them by their glowing colors.
But Freshwater, the student's parents said, also used it to shock their son and other students, branding their forearms with a cross-shaped welt.
