What On Earth Is It? – #24

If you think you know what it really is, or – even better – you have a hilariously silly concept of what it might be (but definitely isn’t), drop us a line and get your suggestion printed in the magazine next month.

    FERROFLUID is a liquid which becomes magnetized in the presence of a magnetic field. We made it for a project last year – we used oil, iron shavings and magnets.

    It may sound very silly, and I wish it could display more photographs, however in my opinion, it looks like a soft, glassy, black, spiky jello. Forgive me if I am being rude.
