Teacher ‘slices’ student in shiver-inducing class experiment

May not be for the overly squeamish.

IT’S GRAND IF it’s for science. A teacher in Russia showed her class a neat little chemical reaction by means of faux-SLICING a student’s arm open.

She rubs the weary-looking student with a solution of thiocyanate ions and scrapes her with a knife covered in a solution containing iron(III) ions.

Their reaction? The appearance of runny red ‘blood’.

Yes, this would make an amazing Halloween trick. Here’s an explainer video.
