Try this at home, it will freak you out!
Apparatus: 1/2 pint milk, 1 small bowl, 1 piece of raw liver (bloodier the better)
If you want to be a real science mook and set up a 'control' you
will also need different piece of meat such as a fillet or
steak, raw of course.
Method: Place milk in bowl on worktop, place raw liver on worktop 4-8 inches away from bowl of milk. Leave for 45 minutes.
Result: The liver 'crawls' to the bowl of milk, and
leaves a bloody trail.
The 'control' won't do a thing. Weird but true.
Enjoy the Holiday!
