ooblick

   and the Oobleck"] n. A bizarre semi-liquid sludge made from
   cornstarch and water.  Enjoyed among hackers who make batches
   during playtime at parties for its amusing and extremely
   non-Newtonian behavior; it pours and splatters, but resists rapid
   motion like a solid and will even crack when hit by a hammer.
   Often found near lasers.


   Here is a field-tested ooblick recipe contributed by GLS:


     1 cup cornstarch
     1 cup baking soda
     3/4 cup water
     N drops of food coloring


   This recipe isn't quite as non-Newtonian as a pure cornstarch
   ooblick, but has an appropriately slimy feel.


   Some, however, insist that the notion of an ooblick *recipe*
   is far too mechanical, and that it is best to add the water in
   small increments so that the various mixed states the cornstarch
   goes through as it *becomes* ooblick can be grokked in
   fullness by many hands.  For optional ingredients of this
   experience, see the "Ceremonial Chemicals" section of
   Appendix B.
