Seventh-grade science teacher John Freshwater has his supporters, but his religious agenda in the classroom has clearly not won over everyone in Mount Vernon, Ohio. At a school board meeting Monday night, he had as many friends as foes in the audience.
Freshwater made headlines several weeks ago when he refused to remove his Bible from his classroom desk. Soon, there were allegations that he was preaching religion in class, distributing creationist literature to his science students, and that he allegedly burned a cross on a student’s arm with an electrical device.
The school district has hired an independent investigator to substantiate or refute the allegations. Freshwater was allowed to continue teaching meanwhile, with an administrative observer in the classroom to monitor him.
The device he allegedly used to burn the student is in fact a hand-held Tesla coil, 
a staple of science education. My students have seen it in action. It can generate high voltage arcs a few centimeters long when held near a ground. While the sparks are not lethal, they can cause pinpoint skin burns that can be pretty painful. I speak from experience.
It boggles the mind why any teacher would subject a student to a potentially painful electrical arc. I tell mine to stay away from the business end of the device, even if they think they’re “tough.”
Besides, the smell of burnt flesh is not all that appealing.
