Hi schooler flushed one down a toilet,wasnt pretty.
Never got caught but the interrogations were intense
No one squealed
Some guy at our HS did that back in ‘63 or ‘64, and it was a flood until the janitors got the water turned-off. School was out for the day and next day, until it was cleaned-up and repaired. We knew who did it, but no one ratted him out, either. We all got grilled by the admins.
