HJ Ferromagnetic Fluid

The ferromagnetic fluid allows you to get a visual representation of the usually invisible magnetic fields that surround any ordinary magnet - it's truly fascinating to see and will "attract" the attention older kids and even adults! Wave the magnet up and down the sides of the test tube or bring it close, then pull it away and watch the nanomagnets line up and wave around as if by magic! Of course, it's not really magic, it's science!
