Magnetic Silly Putty &quot;Hack&quot; Creates Freakish Magnet-
Devouring BlobS  This automagically morphing blob of Silly Putty
is based in science, silly, not witchcraft.  But how does one go
about creating a freaky blob of magnet-devouring goodness?
Instructables member Michael Saurus lays out a parts list:  -
disposable gloves (latex or other) - disposable face mask -
disposable work area (paper plate)  - Thinking (Silly) Putty
($2.00 or less) - any colour - ferric iron oxide powder (artist
supply stores) - neodymium magnet  After that, it's up to you to
follow his simple-yet-amazing/freaky experiment to its
conclusion. Check the video—that hellspawned putty ball eats
magnets! [Instructables]
