In reality, this teacher probably could have drunk an entire bottle of this dry erase cleaner and maybe had a stomachache – that’s about all you would expect. Dry erase cleaner contains either isopropyl alcohol or ethanol and maybe a soap detergent – nothing dangerous. But these kids didn’t know that. That’s what makes poisoning pranks so dangerous – you never know how the poison will affect the victim. I worked at an ice cream shop in high school and one of my co-workers put citric acid solution into a co-worker’s soup and he vomited for a half hour. When they told me about it, I really didn’t think it was funny at all – I frankly got scared and determined to never leave coffee, soup or anything else unattended, especially around those maniacs at the ice cream shop.
