Magnetism makes silly putty fun again  The image above is a
screen capture from a video clip where the black ooze gobbles up
that rare-earth magnet. It’s actually a blob of Silly Putty
which was slightly altered to add magnetic properties.
[Mikeasaurus] grabbed some ferric iron oxide powder from an art
supply store and donned gloves and a dust mask while massaging
it into the silicone polymer. If you get the right mix of the
two materials you end up with a flowing substance that performs
mysteriously when exposed to a magnetic field.  Check out the
video after the break to see some of the tricks that
[Mikeasaurus] can do. The putty really looks like it has a life
of its own. It will stretch a remarkable distance to get close
to the magnets (amorphous stretch). If left in contact with one
it will fully engulf it and then form an orb.  Now, is there any
way to use this with electromagnetic fields to build a morphing
robot?     1. brad says:      first thought: i need to go buy
silly putty and iron filings right
