Three Austrian boarding school students are under investigation on suspicion of serving tea laced with disinfectant and water from the toilet to a teacher who tried to discipline them, Austrian media said on Thursday.

Typical dumb kid reaction to being disciplined, typical meaning very stupid.
Now, they're going to have understand choice/consequence, that for every choice there is a consequence.
The consequence for this choice should be severe, since what they did could literally amounts to attempted murder, if the Austrian police decide to pursue it under that heading.
