Since the dense fluid contains ferromagnetic micro particles, it is attracted by magnets. It gets totally bent out of shape in order to follow a magnet.
<br />This product is an experimental - educational toy for the growing kids, who need to understand what is the magnetic field and how various materials can attract or repel each other.
<br />As soon as a super magnet comes close, it seems as if the Magnetic Dense Liquid Putty comes to life.
<br />Function: Stress relief, fancy
<br />Color: Purple, Blue, Black, Gold, Sliver, Green, Red
<br />The stronger the magnet is, the more impressive are the reactions. We recommend the large cube magnet.
<br />You will also receive a small cube magnet for a simple testing.
