New anti-taser tactic - wet yourself thoroughly with water and a few

Reminds me of my mock Physics practical A level back in nineteen canteen.

I'd been given the problem of measuring the cubic coefficient of expansion of a liquid, using a precision flask
with a capillary stopper. The liquid smelled strongly of paraffin, but a whispered conversation about my result
with the chap next to me suggested that the liquid was in fact water.

When the teacher handed out the results (I got good marks) he admitted that it was water with an added drop of
paraffin.

Very effective at causing confusion....

Good trick.

And further thought has suggested that even really dousing yourself in
petrol might not help - the taser-armed person might assume it was water
with a drop of petrol...
