Thinking Putty magnetic black
Since the putty contains ferromagnetic microparticles, it is attracted by magnets. It gets totally bent out of shape in order to follow a magnet. The stronger the magnet, the more impressive are the reactions of the putty. The putty comes in a practical tin box, but withouth magnet.
Other nice characteristics of Magnetic Thinking Putty:
- Does not contain water and therefore does not dry out
- Does not stick or stain and is not greasy - keeps hands clean
- Is nontoxic and therefore suitable for children 4 years and older (as long as the children only work with the putty - strong neodymium magnets should not be in the hands of children under 14)
