The Wacky World of Superabsorbent Polymers
By: Steve Spangler,
Regis University, Denver, CO
Pour distilled water into an “empty” cup and the
water solidifies into a gel. In another beaker add a
small amount of powder, pour in distilled water and
see an avalanche of fresh powdered “snow.”
Concepts: Polymers, osmosis, cross-linking.

Mystery Nylon Factory
By: Jim and Julie Ealy, Retired,
The Peddie School, Hightstown, NJ
Two solutions are poured together in a beaker. A paper clip
is lowered into the solution. As the paper clip is withdrawn, a
very long strand of nylon is pulled from the beaker.
Concepts: Polymerization, organic chemistry.
Note: Perform this demonstration in a fume hood or wellventilated
lab.

AP2088 Mystery Nylon Factory—Chemical Demonstration Kit $31.30
Super-Duper Polymer Gel
By: Walter Rohr, Retired, Eastchester H.S., Eastchester, NY
When a small amount of a white powder is sprinkled into a liquid
and water is added, it transforms into a thick, viscous gel. When
poured back and forth between two beakers, the gel begins to
take on a life of its own and literally defies gravity by crawling
up and out of the beaker.
Concepts: Polymers, viscosity.
Note: Ethanol or methanol (25 mL per demo) and water are
required and available separately.

Polymers, Polymers, Polymers
By: The Flinn Staff
Introduce your students to the
fascinating world of polymer
chemistry by making “slime,”
polyurethane foam and nylon
and by demonstrating the super
water-absorbent material found
in disposable diapers.
Concepts: Uses and formation of polymers, specifically “slime,” polyurethane foam,
nylon and sodium polyacrylate; crosslinking.
Note: Perform this demonstration in a fume hood or well-ventilated lab.

AP4426 Polymers, Polymers, Polymers—Chemical Demonstration Kit $60.05
Polyurethane Foam System
By: The Flinn Staff
Try this amazing demonstration! Simply mix two viscous
liquids together and watch as the mixture expands to
about 30 times its original volume. The result is a hardened,
lightweight polyurethane foam.
Concepts: Polymers, catalysis.

Pour a Rainbow
By: Steve Spangler, Regis University, Denver, CO
Pour a rainbow of colors from beaker to beaker while students
spontaneously erupt in a chorus of ooohs and aaahs!
Concepts: Polymers, acid–base indicators, hydrogen
bonding.
Catalog No. Description Price/Each
AP5932 Pour a Rainbow—Chemical Demonstration Kit $28.70
Sodium Alginate Polymer
By: The Flinn Staff
Reacting sodium alginate solution with
calcium or copper ions produces a smooth,
flexible, semisolid substance that precipitates
from water in the form of—worms!
Concepts: Polymers, polymer gels, crosslinking,
polysaccharides.

AP7087 Sodium Alginate Polymer—Chemical Demonstration Kit $32.20
Fluorescent “Gummy Worm”
Polymers
In this colorful demonstration, “gummy worm” polymers
are synthesized from sodium alginate and three different
dyes that fluoresce when exposed to ultraviolet light.
Concepts: Polymers, cross-linking, fluorescence.
Note: An ultraviolet lamp is required and available
separately.
Catalog No. Description Price/Each
AP7513 Fluorescent “Gummy Worms” Polymers—
Chemical Demonstration Kit
$33.15
AP9030 Ultraviolet Lamp, 18" 47.10
Water Marbles
By: The Flinn Staff
Amaze your students by “floating” a steel sphere on
“water.” Since the water marbles have essentially the same
refractive index as water, the steel sphere will appear to
float on the surface of the water.
Concepts: Superabsorbent polymers, index of refraction,
discrepant event.
