OOHHBLIC
Introduction:
OOHHBLIC is amorphous. It has the properties ofa solid and
a liquid, similar to glass, silly putty, certain rubbers and
various plastics. The polymer is created when the the water
makes all the cornstarch molecules bond together, much like
the slime and silly putty experiments.
Materials:
- 1 box of corn starch
- ~250mL of water
- A 1000mL beaker
Procedure:
Empty the box of corn starch intothe lieter beaker. Add water
slowly, mixing well with your hand. Add only enogh water
to make the cornstarch gel-like. The cornstarch will have
the physical properties of both a solid and a liquid. It
will pour like a liquid but break like a solid. You will
be able to jab it and it will be rigid like a solid, but
push gently on it with your finger and it will sink like
a liquid.
Helpful Hints:
- Be sure to use your hand when mixing as
a stir stick is too fragile and a spoon will be too awkward.
- Be
sure to use a beaker/container large enough to fit your
hand.
- Corn starch is water soluble and can be
easily cleaned up with a wet rag or rinsed down the drain.
