Setting An Example
On the first day of the new school year, this teacher wanted to make it crystal clear to her students how crucial it is to follow the rules in the science lab and to wear all of the proper equipment by showing them what could happen if they try to disobey.
How did she do this? By dropping a cow’s eyeball into a bottle of acid just to have the class watch the eye deform, which gave them nightmares for weeks. At least the class was sure to keep their goggles on every time they entered the lab. No rules were broken after that terrifying example.
